| 摘 要： | 碾压混凝土重力坝结构简单,施工方便,应用广泛。在实际工程中,经常会遇到地基的各向异性问题。应用非线性有限元结构分析软件ABAQUS,以某碾压混凝土重力坝的岸坡坝块为研究对象,建立了碾压重力坝的三维有限元计算模型。在正常蓄水工况下设置了六组水平向与铅直向弹性模量比值不同的计算组,通过对比分析,研究其可不考虑各向异性的材料比值区间。

| Abstract: | RCC gravity dam has a simple structure, can be constructed conveniently, and is widely used nowadays. In practical engineering, foundation anisotropy problems are often encountered. In this paper, we used the finite element analysis software ABAQUS, took the slope dam blocks of a roller compacted concrete gravity dam as the basic computational structure, and established a 3D finite element calculation model of RCC gravity dam. Under the normal storage condition, six different calculation groups were set that have different ratios of horizontal to vertical elastic modulus. Through comparative analysis, we studied the material ratio range within which anisotropy needs not to be considered. |
