벽체강성변화에 따른 다층성 사질토지반의 거동특성에 대한 실험적 연구

The typical pressure distribution' by foreign empirical relationship has been used on designing the braced excavation in domestic. There are many problems in using the empirical pressure distributions developed by the foreign investigators, because the conditions of soil strata are different from those of our country. Many problems in constructing the braced excavation on the downtown areas are occurred due to damages of adjacent buildings. Most problems are mainly related to the drainage, displacement and settlement. The effects on the wall by the magnitude and location of the surcharge are not examined clearly to the present. In this study model tests were performed to evaluate the effects of multi-layer, magnitude and location of surcharge.
