重力坝抗滑稳定计算安全系数法与分项系数法差异研究

Study on the difference between safety factor method and partial coefficient method for gravity dam anti-sliding calculation

我国现行重力坝稳定计算方法主要有水利行业要求的安全系数法和电力行业要求的分项系数极限状态设计方法,都用来表示重力坝的安全度,但计算结果往往不一致。基于此,文章从理论分析和实际工程验证两个角度对两种计算方法的差异进行了对比。

The current calculation methods for the stability of gravity dams in China mainly include the safety factor method required by the water conservancy industry and the limit state design method required by the power industry,which are used to express the safety of gravity dams,but the calculation results are often inconsistent.Based on this,the article compares the difference between the two calculation methods from two angles:theoretical analysis and actual engineering verification.
