摘  要:
本文以辽宁省内某座已建水电站的混凝土重力坝为例,按照刚体极限平衡条件,分别用定值法和可靠度分析法计算了该坝的抗滑稳定安全度。在可靠度分析中考虑了岩石抗剪指标及混凝土容重γ的随机性,对重力坝抗滑稳定的影响,因而,对比这两个方法的计算结果,可以证明可靠度分析法能比定值法更全面,更客观地反映了重力坝工作的可靠性。

摘  要:
By the aid of the example which is the concrete gravity dams of one existing hydroelectric station in Liaoning Province, this paper computed against sliding stability of this dam according to the condi- tion of rigid body ultimate balance, separately by use of the reliabi- lity analysis and deterministic method. In reliability analysis, the random of bed rock shear index and unite weight of concrete have an influence on gravity dams against sliding stability,therefore,to contr- ast these results of two method may prove that the methodof reliability analysis can reflect more entirely and more objectively the reliability of gravity dams in its operation than deterministic method.
