摘要
在同马大堤一标段防渗墙施工过程中 ,堤身出现规模不等的裂缝。介绍了堤身存在裂缝情况下 ,汛期水位骤降时堤防迎水坡抗滑稳定性的计算过程。重点探讨了堤坡稳定分析中工况选择、计算参数选取和强度参数敏感性分析的思路和依据。
Various scales of cracks occurred in the Tongma levee body during the construction of diaphragm wall. The stability of the riverside slope of the levee during the flood period is thus seriously concerned. This paper introduces the calculation process of the stability analysis under the condition of sudden drawdown of the water level . The selection of operating mode,calculation parameters and the sensitivity analysis of strength parameters are mainly discussed. The result of this paper has provided basis for the engineering treatment to the levee cracks.
