摘要
通过对一个坝址地质结构较为发育的拱坝作三维有限元非线性分析,分析了温度、渗流,地形地貌,地基上的地质缺陷等对拱坝及大坝运行时地基的力学行为的影响。并给出了复杂地基的拱坝的位移场、应力场的分布规律和传力特性。对大坝及基岩上塑性区产生的机理,形式和发展趋势作了分析。
By means of 3D FEM non-linear analysis of an arch dam having a dam toe with developed geological structure, the influence is discussed of temperature,seepage,terrain and geological flaws in the foundation on the arch dam and mechanical behaviors of foundation when the dam is working. The distribution of the displacement field,and the stress field of the arch dam with complex foundation and characteristics of the transmission of forces are given. The mechanism of the generation,form and development of plasticity domain in dam and bedrock are analyzed.
