| 摘 要： | 用可靠度理论的验算点法和弹粘塑性结构面的块体理论推导了被结构面和临空面贯穿切割的岩石块体结构的可靠度计算公式,并编制了相应的计算程序。计算工作量较随机有限元法大为减小,精度可满足设计要求。可用以分析岩坡、岩石坝基、地下洞室等三维块体结构的可靠度。

| Abstract: | This paper presents the reliability calculation algorithm for rock block structure, which is based on the combination of clastic-viscoplastic block theory and " design point method" of reliability theory. A related computer program is compiled. The calculating accuracy of the proposed algorithm can meet the requirement of engineering design, but the calculating work of the algorithm is much less than that of normal stochastic finite element method. Therefore, it can be applied to the reliability analysis of three dimensional rock block structures, such as,rock slope, dam foundation and underground opening. |
