The retaining wall reclining on the slight slope built on soft foundation is usually used in protecting the shore of river, the contradiction between the lack of impartiality in stress of the base and the small stress allowed by the foundation as well as the lack of stabilization of the breast wall is a hard nut to crack in the engineering. in the paper, a tenon - base is added under the base of the retaining wall, on the study of the choice of the parameters and formulas used in calculation and the research of theory used in calculation, method used to deal with the load, etc, the writer gives a way to crack the nut mentioned above paragraphs and presents a qualitative and quantitative analysis about them, such as the equivalent inner friction - angle ( d ) and the passive press of the clay ( ep ), etc. in the end of the paper, using modern optimization method, a design of the retaining wall reclining on the slight slope built on soft foundation is done, the result is economical, and accords with the fact
軟基上的仰斜式擋土墻在水利工程河道護岸中經常遇到，仰斜式擋土墻基底偏心應力較大和軟基土地基容許承載力偏小的矛盾以及擋土墻抗滑穩定不足是工程中難以解決的難題。本文在對仰斜式擋土墻設計中有關計算參數的選擇、公式的選用應該注意的問題進行了研究，對河道護岸軟基礎上的仰斜式擋土墻採用凸榫基礎處理的方法，就其計算理論、設計驗算中各荷載的具體處理方法進行了較為細致的研究，提出了解決軟基礎上的水工仰斜式擋土墻難以解決的難題的方法，並對有水情況下粘土等效內摩擦角_ d 、凸榫被動土壓力e _ p等在計算中的取值提出了定性和定量的分析。最後利用現代優化方法對軟基礎上的水工仰斜式擋土墻進行了結構優化設計，得出了符合實際的結果，與其它重力式擋土墻形式進行比較，取得了明顯的經濟效益。 -
