황진성(Jin-Sung Hwang) 한국산업융합학회 2002 한국산업융합학회 논문집 Vol.5 No.1

The purpose of this study was to predict the future urban activities effectively and rationally. For the purpose, a simulation model, based on SD, was built by integrating economic activities, land use and traffic of a city and by dividing Daegu Metropolitan City into seven districts and one county. To identify the effect of the development of a new city in the Dalsung County area, the future population and traffic volume of the city were predicted, using the model. The results are summarized as follows. The future population according to the development of a new city in the Dalsung County area was predicted, and the effects before and after the development twenty years later were compared. The future population of the Dalsung County was found to have slightly increased, whereas that of the adjoining Dalsuh Metropolitan District was found to has slightly decreased. For the other districts, there were no changes of the future population. It was found, therefore, that the development of a new city would have no effect on other districts. Then, the traffic volume according to the development of a new city in the Dalsung County area was also predicted. It was found that in the initial stage the traffic volume would increase with the increase in population of Dalsung County. It was predicted that particularly. the traffic volume for the purpose of business would greatly increase. The traffic volume of Dalsuh Metropolitan District showed a slight decrease, whereas for the other districts, there were no changes of the traffic volume.<br/> <br/>

본 연구는 본격적인 목재수확시기에 대응하여 대형화되어 가는 목재운송차량의 원활한 통행과 노체 피해 방지를 위해 산림기술경영연구소 관내 연약지반을 대상으로 토목섬유를 활용한 노반 조성 후 시간경과에 따른 노면지지력 변화와 대형 목재운송차량의 통행 횟수 증가에 따른 노면지지력 및 침하량 변화를 분석하였다. 그 결과, 노반 조성구간의 경우 약 1년의 시간경과 후 노면지지력이 양호판정기준인 CBR 15% 이상으로 안정화 되어 가는 것으로 나타났으며, 토목섬유별 처리효과는 큰 차이를 보이지 않는 것으로 나타났다. 또한 노반 조성구간에서 대형 목재운송차량의 통행이 최대 300회 이루어진 이후에는 침하량이 허용기준 50 mm 이하로 안정되고, 노면지지력 또한 CBR 20% 이상으로 향상되는 것으로 나타났으며 노반의 두께별로는 큰 차이를 보이지 않았다. 그러나 토목섬유를 활용한 노반을 조성하지 않은 구간에서는 허용기준 이상의 침하와 함께 노면의 지지력은 대형 목재운송차량의 통행이 불가능한 것으로 나타났다. 따라서 대형목재운송차량의 통행을 위한 연약지반의 노면지지력 보강을 위해서는 토목섬유를 부설하고 노반을 최소 0.2 m 이상 조성하는 것이 필요하다. This study was carried out to provide surface bearing capacity reinforcement of forest road by sub-base facilities based on a soft ground use of geosynthetics to prevent the damage of the road surface passing heavy logging trucks and to pass smoothly heavy truck against growing timber harvesting. The analysis of the road surface bearing capacity as progressing time and the increase of the number of passage of heavy logging trucks were conducted experimental section of forest road on the soft ground in the Forest Technology and Management Research Center. As a result, it was found that the road surface bearing capacity were stabilized at CBR of 15% or more, the effect of reinforcement by type of geosynthetics showed no significant difference after the lapse of about 1 year. After reaching the passage of 300 times for the heavy logging trucks on the sub-base construction section, the settlements was stabilized below the allowable standard of 50 mm, road surface bearing capacity also improved to more than CBR 20% and there was no significant difference in the thickness of the sub-base. However, in the section where the sub-base is not constructed, it is found that the lack of surface bearing capacity with the settlements more than the allowable standard is not possible to pass the heavy logging trucks. Therefore, in order to reinforce the road surface bearing capacity of the soft ground for the passage of the heavy logging trucks, it is necessary to construct a sub-base of at least 0.2 m when using geosynthetics.

본 연구는 목재운송 효율을 도모하기 위하여 목재운송차량이 대형화 되어감에 따라 대형 목재운송차량의 원활한 임도 통행을 위한 노면지지력 확보할 수 있는 노반 시설기준을 마련하고자 실시하였다. 산림기술경영연구소 관내 연약지반 임도 노면에 대하여 토목섬유를 활용하여 적정 골재배합비로 조성한 노반의 두께별 노면지지력 강화효과를 분석한 결과는 다음과 같다. 토목섬유를 활용하여 상굴식으로 노반을 0.2 m 이상 포설한 시험구간은 노면지지력이 CBR 15% 이상으로 양호한 것으로 나타났다. 그러나 토목섬유 종류별 노면지지력 보강효과는 큰 차이가 없었고, 상치식으로 조성한 구간의 경우 노면지지력이 미흡한 것으로 나타났다. 따라서 연약지반 구간에서는 상굴식으로 터파기 한 후 토목섬유를 부설하고, 노반층 두께를 0.2 m 이상 조성한 후 표층을 포설하여야 대형 목재운송차량의 원활한 통행에 필요한 노면지지력 확보가 가능할 것으로 판단된다. This study was carried out to establish the standard of sub-base facility which can strengthen road surface bearing capacity for smooth passage of logging trucks in forest road as the size of the logging truck has been increased in order to improve the efficiency of timber transportation. The results of reinforcement effect analysis of the surface bearing capacity by the thickness of sub-base prepared with the optimum aggregate mix ratio using geosynthetics for forest road on the soft ground in the Forest Technology and Management Research Center are as follows. The surface bearing capacity of CBR exceeding 15% was found to be sufficient when the sub-base was constructed over 0.2 m depth of laying gravels with installation of geosynthetics after digging out subsoil. However, there is no significant difference in reinforcement effect of surface bearing capacity by types of geosynthetics. And, it was found that the surface bearing capacity was insufficient in the installation of sub-base. Therefore, in the case of soft ground, It is possible to secure the reinforcement of the surface bearing capacity for the smooth passage of heavy logging trucks by sub-base, that was constructed over 0.2 m depth of laying gravels with installation of geosynthetics after digging out subsoil.

This study was conducted to analyze accessibility and reduction effect of forest operations cost before and after forest road construction based on actual silvicultural operations in 5 regional forest service(8 management planning district) where forest operations was enacted consistently. The result show the accessibility and the reduction effect of the operation cost, the accessibility of forest operation area within 500 m from forest road or public road increased about 3.2 times after the forest road construction. The reduction effect of the operation cost was averagely 576,000 won/km/year. According to the results, forest road had an effect on improvement of accessibility and reduction effect of forest operation cost. This result could be offered basic information to support policy of forest road expansion.

This study was conducted to analyze the effect of forest road network on accessibility and cost reduction for forest operations before and after forest road construction by investigating harvesting operations in 5 regional Forest Services (8 management planning districts). The results showed that the accessible operation area within 500 m from forest roads or public roads increased about 3.5 times after the forest road construction. The average cost reduction was 308,000 won/km/year. According to the results, forest road had a great effect on improvement of accessibility and reduction effect of forest operation cost. Therefore, the policy for expansion of forest road should be continued for preparing of effective harvesting system.

This paper measured some condition about differential height of two points for the comparison of measure by direct method and Geodimeter and trigonometric Leveling method. The research was compared relationship between the volue to get from three measure method and five measured man. The significance of between three measure method and five measured man has been investigated by analysis of two-way ANOVA. The result indicate that between five measured man show insignficance, and between the direct method and Geodeter method show signficance and between the direct method and trigonometric Leveling method show signficance but between the Geodeter method and trigonometric Leveling method, two method show insignficant. Therefore, when using Geodemeter leveling method and trigonometric Leveling method, you must keep particular attention when former two Leveling method about instrumental error, natural error, and personal error, two Leveling method using low precision leveling.
