| 摘 要： | 应用可靠度理论对混凝土重力坝进行结构稳定分析,方法采用一次二阶矩法。通过计算机编程,计算出了某重力坝基面抗滑和抗压两个极限状态的可靠度及相应的失效概率。结果与蒙特卡罗法计算结果对比分析相差在1%以内。说明一次二阶矩法可以作为混凝土重力坝可靠度的计算方法。

| Abstract: | Reliability theory and AFOSM are applied to analyze the structure stability of the concrete gravity dam in this study.The reliability and corresponding failure probability against sliding and compression are found out for both limit states on surface of gravity dam by using computer program.Compared with the results calculated in Monte Carlo method,the difference is less than 1%,indicating that AFOSM may be applied as the method to calculate reliability of the concrete gravity dam. |
