摘要

摘要: 分别采用圆球、椭球以及非均匀有理B样条模拟边坡的三维滑动体,利用三维简化Janbu法计算给定滑动体的安全系数,采用混合粒子群算法搜索临界的滑动体及其对应的安全系数。对某两个典型土坡按不同模拟滑动体策略对计算结果的影响进行比较,并分析NURBS中不同跳动点个数的耗时及其对计算结果的影响。

Abstract: Spherical and ellipsoidal surfaces and also the non-uniform rational B-spline(NURBS) are adopted to simulate 3D sliding bodies of slopes;the mixed particle Swarm Optimization algorithm is used to locate the critical sliding body and its corresponding factor of safety given by simplified three-dimensional Janbu method.The effects of different simulating procedures on the results are studied for one typical soil slope.In addition,it is analyzed time consumption of the number of changing points in NURBS and its effect on the results.
