碾压混凝土重力坝失稳破坏机理的初步分析

Study on failure mechanism of roller compacted concrete fravity dam

本文采用弹塑性有限元法，对碾压混凝土重力坝层面上的应力、点安全系数分布及沿层面失稳破坏的机理与过程进行了初步的分析，取得了一些可供进一步研究碾压混凝土重力坝稳定性和安全度标准，及工程设计参考的意见．

By means of the elastoplastic finite element method, this paper preliminarily analyses the stresses, distribution of safety factor, mechanism and process of the failure along the bedding of roller compacted concrete gravity dam (RCCGD).The result may be referred to further studies of the stability and safEty standard of RCCGD as well as engineering design.
