| 摘 要： | 无限岩土介质中静水压力作用下圆形隧洞围岩的应力位移分析是地下工程的一个经典问题.文章以材料模型为主线,结合不同的屈服准则和塑性流动法则,对近年来求解该问题解析解或闭合解的文献和取得的成果进行了系统的归纳总结和评述;重点介绍了常见的弹性-理想塑性模型、弹-脆-塑性模型和弹性-应变软化模型及其结合Mohr-Coulomb准则和Hoek-Brown准则得到的主要分析结果;同时介绍了弹-塑-脆-塑性模型、黏弹性模型等材料模型的最新研究进展.

| Abstract: | Theoretical analysis of ground response to circular excavations subjected to hydrostatic pressure in rock mass is a classical problem in underground works.In the past decades,several solutions have been obtained by considering different strain-stress behaviour of rock mass,which are summarized and observed in this paper combined with various yield criterions and flow rules.Three frequently used conventional models,including elastic-perfect plastic model,elastic-brittle-plastic model and elastic-strain softe... |
