擁壁에 作用하는 主動土壓의 變動에 關한 硏究 = A Study on Variation of Active Earth Pressure

다국어 초록 (Multilingual Abstract)

In the development of engineering designs, decisions are required irrespective of the state of completeness and quality of information, and are formulated under conditions of uncertainty. Furteremore, under conditions of uncertainty the design invoke risks. Thus, in the design of the structures, currently used deterministic design methods do not provide a realistic assessment of the actual safety or the reliability of the structures. It is desirable that decisions required in the process of the design invariably must be made based on the reliability analysis. Properties of soil material are subject to more uncertainty than those of other structural material. In order to simplify the reliability analysis or the reliability-based design process of the structures associated with the active earth pressure, it is necessary to find the variations of the active earth pressure by using the basis properties of soils.
Monte Carlo simulation is perfomed to obtain the relationship between the variation of the active earth pressure and the soil properties.
A series of multi-linear regression equations is sugested in this paper and the sensitivity of the basic soil properties to the variation of the earth pressure is investigated.
