摘要
综合运用岩石块体的自动识别方法、岩体网络无压渗流分析方法和弹粘塑性块体理论 ,成功地分析了小湾拱坝坝肩岩体的渗流场和应力场 ,得出了坝肩岩体变形与屈服区分布规律以及稳定安全度评价 .结果表明 ,弹粘塑性块体理论作为一个比较完善的系统 ,不仅前处理简单 ,计算精度高 ,而且能模拟复杂的地形地质条件 。
The whole system of elastic_viscoplastic block theory of jointed rock masses is introduced. The methodology is composed of the automatic identification technique, the network seepage analysis method, and the elastic_viscoplastic block theory. Through its application to the Xiaowan arch dam abutment, the deformation and stress distribution as well as the safety factor are obtained. The methodology proposed can be widely used because of its simple preprocessing, high accuracy and its feasibility of dealing with complicated topography and geology.
