本研究目標，是嘗試深入探討利用FLAC軟體進行數值分析，建物加載於c- 土壤邊坡之應力傳遞與位移分佈。
第一部分著重於偏黏質邊坡，在建物退縮距離s/B=1/8時之應力傳遞與位移分佈；第二部份則延伸至建物退縮距離s/B=1/4、1/2、1時之情況進行研究；第三部份則比較偏黏質邊坡與偏砂質邊坡之應力傳遞與位移分佈情形。
分析結果顯示，在偏黏質邊坡與偏砂質邊承受小載重時，坡趾以上至基礎下方之間，其等值主應力增量(Δσ1)分佈是非常相似的；當載重增加至非彈性階段時，偏黏質邊坡之等值主應力增量(Δσ1)分佈會有扭曲情形發生，偏砂質則否；因此將上述所發生之情況，建立一套管理基準質，供工程界參考。

The aim of the paper is tried to fully understand the stress propagation and displacement distribution of both clayey slope and sandy slope due to foundation. Numerical simulations using FLAC is performed in the study. The first part of the study focuses on the stress propagation and displacement distribution near foundation and slope with a setback s/B=1/8. The second part extends the setbacks s/B to 1/4, 1/2 and 1. The third part focuses on the comparison both stress propagation and displacement distribution between clayey slope and sandy slope,
The analytical results show that equalized contours of the principal stress increment (Δσ1) propagation in soil between toe of slope and foundation is roughly same if load is small and the behavior of load-settlement is elastic. Then equalized contours of the principal stress increment (Δσ1) will be apparent distorted in clayey slope but not in sandy slope if load increases to make the behavior of load-settlement is inelastic. The management levels related to slope instability are analyzed.
