摘 要: | 本文研究拱坝的失效模式与可靠度.针对某拱坝,首先完成随机变量的统计量,然后,应用三维随机有限元法,在算出该坝的点可靠度的基础上,探讨了坝体与坝基联合作用下,开裂的可能性,并得出开裂深度与可靠度的关系.通过建立在条件概率基础上的体系可靠度公式,找出拱坝的最大可能失效模式与相应的可靠度.

Failure Mode and Reliability of Arch Dams |

Abstract: | After completing the evaluation of the statistics of the random variables for a specified arch dam,and obtaining the results of the reliability for the Interesting points by three dimensional random finite element method,probable crack of the dam and the foundation is studied and the relationship be- tween the depth of crack and reliability of the dam is found.Finally the possible failure mode and the corresponding reliability of the dam are obtained by the system reliability formula from the conditional probabilistic theory. |
