重力坝抗滑稳定性分析

安全是水坝的头等大事。重力坝失事往往是由于滑动导致的,因此抗滑稳定问题是大坝稳定的主要问题,本论文主要运用刚体极限平衡法和有限元法对某重力坝进行安全稳定性校核。刚体平衡法是一种传统的稳定分析方法,这一方法是经过工程实践检验的,所得的安全系数一直以来被作为判断大坝安全度的主要依据。有限元法是近年来随计算机科学的迅速发展和岩土力学的基本理论水平不断提高和发展起来的一种新方法,本文分析比较了两种方法的优缺点,进一步证明了有限元法更符合重力坝的实际情况。

Analysis of the Anti-sliding stability of the gravity dam

Dam safety is a top priority.The gravity dam failure usually led by slide,the anti-slide stability is the stability of the dam's main problem;this paper mainly checks the safety stability of the gravity dame with both the rigid body limit equilibrium method and finite element method.The former is a traditional method which is the practice of engineering,and its safety factor has been used as a judge of the dam safety.In the recent years,the finite element method the latest technique is more and more applied,with the rapid development of computer science and rock mechanics of the basic theory.This paper compares the advantages and disadvantages of both approaches;the later more fits the actual situation of the gravity dam
