基于ANSYS模拟的某拱坝坝与地基整体稳定性分析

摘要

The arch dam stability mainly depends on the reaction force action on both sides of the arch side , the overall stability of the dam and its foundation is an important guarantee safety of the project;the upstream water pressure was increased stepwise method (method overloading),through ANSYS Numerical simulation of the overall stability of a planned high arch dam and foundation of the quantitative calculation analysis ,the corresponding stress deformation law for subsequent dam project provides a scientific basis for decision-mak-ing.%拱坝坝体的稳定主要依靠两岸拱端的反力作用，其坝体与地基整体的稳定性是工程安全的重要保障，本文采用逐级增加上游水压力的方法（超载法），通过ANSYS数值模拟技术对我国某拟建高拱坝坝与地基的整体稳定性进行了定量计算分析，得出了相应的应力变形规律，为工程后续坝址决策提供了科学依据。
