现有重力坝设计规范规定采用材料力学法进行重力坝应力分析作为确定坝体断面的依据，但现有规范上的材料力学法和传统材料力学方法不完全一致，为此，根据传统材料力学方法对规范上的材料力学法的重力坝应力分析进行了改进，并对计算中涉及的应力正负号、剪应力积分和剪力合力之间的关系以及如何考虑扬压力等几个不明确的问题进行了讨论。
現有重力壩設計規範規定採用材料力學法進行重力壩應力分析作為確定壩體斷麵的依據，但現有規範上的材料力學法和傳統材料力學方法不完全一緻，為此，根據傳統材料力學方法對規範上的材料力學法的重力壩應力分析進行瞭改進，併對計算中涉及的應力正負號、剪應力積分和剪力閤力之間的關繫以及如何攷慮颺壓力等幾箇不明確的問題進行瞭討論。

The method of strength of materials is used as the tool of gravity dam stress analysis in existing gravity dam design codes to determine dam section. But the method of strength of materials in existing codes are not completely consistent with traditional method of strength of materials. The traditional method of strength of materials is used to improve the method of strength of materials in existing codes for the stress analysis of gravity dam, and several uncertain problems, such as the analysis of stress involved in plus or minus, the relationship between shear stress integral and shear force and how to consider the uplift pressure, are also discussed.
