【摘要】 根据土层剖面的随机场模型和简化Bishop法对一软基上防水墙后岸坡进行了可靠度分析。采用JC方法分别计算了不同软基加固方案所对应的复杂土坡最小可靠指标minb,探讨了土性指标的概率特性和相关性对可靠指标b的影响,根据实测的静力触探成果估计了抗剪强度指标c,j的自相关距离ud,并评价了ud对土坡稳定可靠度的影响,编制了相应的程序,得出了有益的结论。更多还原

【Abstract】 Based on the random field modeling of soil profile and the Bishop routine solution,the stability reliability of a practical complex slope behind waterproof wall is studied. By JC method,the reliability index b of different improvement plan for soft foundation is respectively calculated. The influence of probabilistic property and cross-correlativity of soil properties on reliability index is analyzed. From the results of static cone penetration test,the self-correlation distance ud of c and jis estimated,and the influence of udon slop stability reliability is investigated. The developed computer program on reliability of the complex slope stability is worked out and some valuable conclusions are drawn.更多还原
