| 摘 要： | 通过对重力坝的受力分析,得到结构的荷载效应S及结构的抗力R。为建立重力坝抗滑稳定的结构可靠度模型,文章根据结构可靠度理论,建立了功能函数Z与R、S之间的直接关系,即Z与上、下游水位H1、H2之间的直接关系,从而分析结构是否满足可靠性要求。推导的结果还表明了,可以适当的通过增加上、下游坝坡坡率来增加Z的值。

| Abstract: | The structural load effect S and the resisting force R are obtained through analyzing the force condition of gravity dam.In order to estabilish the model of structural reliability for the analysis of stability of gravity dam against sliding,the immediate connection among the function Z, R and S, that is,the immediate connection among Z,the upstream water level H_1 and the downstream water level H_2,is established according to the structural reliability theory. Based on the above relationship,whether the structure fits the condition of reliability can be analyzed. The result also shows that the value of Z can be increased by enhancing appropriately the upstream and downstream slopes. |
