Soil is one of the material that have been used for civil engineering. Soil slope is constructed unavoidably because fill and cut is repeated during construction. If most of structure is destroyed, it causes great loss of life and economic loss. Especially, the stability of soil slope is very important because most of structure has a soil slope. However, Though a study about stability of soil slope has been advanced, soil slope is being destroyed continuously. In fact, a precise analysis of slope failure is impossible because, slope failure has a very complicated and combined mechanical relation. So, many scholars and civil engineers have analyzed a stability of slope by 2-D plane on the basis of plane-strain condition. It means that failure of slope occurs equally on any section of soil slope but, very important fact is failures have a finite width and shape of failure and mechanical relations are different for location of section. Therefore, 3-D spatial idea must be introduced to modeling for probable analysis of slope stability. In this study, an assumption that failure block is a part of sperical shape which has an arbitrary center point and radius is introduced and the computer program, 3DSSA(3-Dimensional Slope Stability Analyzer), is developed on the basis of the circular arc method(∮=0 method). For using 3DSSA, the chart of 3-D stability number is made for many geometrical conditions of cohesive soil slope that pore water pressure is not considered. Through the analysis of finite simple cohesive soil slope, the results obtained by means of the computer program 3DSSA show that: 3-D factor of safety is 1.41 times larger than 2-D factor of safety for most case of soil slope. 3-D stability number converges at 0.128 as angle of slope increase from 7.5。 to 60。. When angle of slope is 60。, 2-D stability number calculated by 3DSSA is smaller than Taylor's(1948) by 5.6 percent. The changes of cohesion and unit weight of soil affect little the ratio of 3-D factor of safety to 2-D factor of safety.

김팔곤 圓光大學校 1981 論文集 Vol.15 No.1

In this thesis it is intended to clear what the fundamental spirit of Korean ethical view-point which had ben keept in the hearts of Korean people was. In chapterⅠit is considered what kind of god the Great God, Master of Heaven which appeared in the Tangoon-myth, Korean origial myth was and what kind of spiritual state, the spiritual ecstasy, fundamental emotion in the myth was. In chapter Ⅱ it is considered what the fundamental spirit of esthical view-point which had been influenced by ancient Buddhism or Confucianism, imported roligion was. In chaper Ⅲ the fundamental spirit of Korean ethical view-point considered in chapterⅠand Ⅱ being summarized briefly, it is considered what the fundemental stand-point of the present scientific ethics is and, then, how both the fundamental spiritof Korean traditional ethical view-point and the stand-point of the present scientific ethics can harmonize well each other.

Even though STD test based on Terzaghi's 1-D consolidation theory is extensively used to estimate the consolidation constant of soft-clay, it takes too much to perform the test in addition to the problem in estimation of C_v and preconsolidation pressure. To overcome these defects, several types of rapid consolidation test, e.g., constant rate of strain test (CRS) an controlled gradient (CG), are proposed. Because consolidation characteristics obtained from the results of CRS test depend on the rate of strain, it is required to determine the variation rate on the basis of the physical and structural characteristic in a building site, and then perform the test. Several methods determining the rate of strain, e.g., ASTM standard, Smith and Wahls' equation in 1969 and Armour and Drnevich's equation in 1986, have been researched. However, the rules about consolidation rates described in ASTM consider only summary of the rate rules as a trial and error an its criterion also depends only on LL value.

Korea enters a new era of industrial modernization, spurred by her successive five-year economic development plans. The labor-intensive light industry that led the nation's economy in the past decades is undergoing a gradual shift to the technology-intensive heavy and chemical industry. The demand for industry-minded young technician is thereby ever mounting in number in various industrial sectors, which in turn creates many challenging issues on Civil Engineering Education. Among them, this paper deals exclusively with the curriculum of the Department of Civil Engineering Education. As the results of a trade analysis for graduates from technical high schools, it was realized that current curriculum were somewhat isolated from outside environment and found too rigid to meet the changing requirements. Needless to mention, teachers play a vital roles in the technician education. Accordingly the teacher must be qualified well not only in knowledge on the major subjects but also in practices. The improvement of current curriculum is strongly recommended to produce qualified teachers, taking into account the changing social demands. This study is very limited in terms of finance, time allowance and manpower. Accordingly the model curriculum was based on the trade analysis, social requirements and the current curriculum, and its justification was not verified by tests and broad reviews.

Strip Area의 水平應力을 考慮한 深度別 壓密沈下

金八圭,林熙大 충남대학교 공업교육연구소 1980 論文集 Vol.3 No.2

This paper develops new equation for predicting in-situ consolidation settlement at any depth of a Strip Area subject to a Uniform Pressure and describes the laboratory procedures used to validate the equation. In order to calculate consolidation settlement at any depth, the depth of clay layer was divided into n equal parts of thickness Δz and the vertical stress was determined, based on the Boussinesq solution. Prediction of consolidation settlement is normally based on the results of one -dimensional Oedometer tests using representative samples of the clay. Due to the confining ring the net lateral strain in the test specimen is zero but in many practical situations, however, appreciable lateral strain will occur and the initial excess pore pressure will depend on the in -situ stress conditions. Applying the Bussinesq solution and the Skempton -Bjerrum method which took the lateral strain into account, a new equation was derived that can be used to calculate consolidation settlement at any depth for a Strip Area carrying a Uniform Pressure. The equation proved to predict the consolidation settlement at any depth more closely to the actual field conditions than have previously known equation.

Shin Wi (pen name: Ja-ha, 1769∼1845) was one of the 'master poets' who wrote their poems in Chinese during the five hundred year period of the Yi Dynasty. He was also an outstanding calligraphist and painter. In the preface to Collected Poems of Shin Ja-ha, Kim Taek-yeong, the editor, says of the origin and characteristic features of Jaha's poetry as follows: Su Shih (1036∼1101) was the poet's master. He was also indebted to Hsu Ling (1507∼1583), Wang Wei(1699∼762) and Lu Yu(1125∼1210). At times rapid, rugged and full of fantasy, his poems soon displays their fine, simple and flat qualities. They employ a thousand feelings and natural aspects so that the reader is dazzled and intoxicated by the brilliant arrangement of dancing words. Indeed the poet was the greatest master of everlasting ages that was ever soaring with the wings of a rare genius. Jaha left about four thousand pieces of verse behind him. among the representative works are forty piece Sookbu in which Korean sijos were translated into Chinese, thirty-five piece Verses Commenting upon Korean Poets in which Chinese poems written by Koreans were evaluated in the form of verse, fifty piece Sundry Poems which has been favorably compared with Po Chu-i's (77 2∼846) 'New yueh-fu', twenty piece Post Chiu rhyu Poems, an imitation of Wang Shih-chen's (1634∼1711) work in the same title, and twelve piece Gwangeuk-jeolgu, a valuable document on the drama and actors of his days. In Collected Treaties Commemorating Dr. Kim Jong-wo's Sixtieth Birthday (Feb. 1977) is carried "A Study of Jaha's Soakbu" by the present author. The study was based on the twenty-three pieces of Soakbu included in Kim Taek-yeong's Collected Poems. Recently, this author had the fortune of obtaining sixteen-volume Gyeongdang Complete Works that contained the complete forty pieces of Soakbu. This paper deals with all the forty pieces in Vomume X, examining them in matters of form and content and analyzing the theories behind the poet's translation of sijos.
