| 摘 要： | 摘要滑移线理论是求解地基极限承载力、挡土墙土压力的理论基础,是以Mohr-Coulomb屈服准则建立的.本文考虑岩体的非线性破坏特性,参考Serrao的研究成果,基于Hoek-Brown经验强度,完善了适于完整、软弱、破碎等均质岩体的滑移线理论,从而为滑移线法求解岩基极限承载力和挡墙压力奠定了基础.

| Abstract: | Characteristic theory is very important in rock and soil plastic mechanics, which is expressed with Mohr-Coulomb strength criterion and is often used to determine ultimate bearing capacity and soil pressure. On the basis of Serrano'work and considering non-lineal failure of rock masses, the authors give the modified characteristic theory system based on Hoek-Brown strength criterion for isotropic rock mass. In order to explain the method, an example is offered in the paper. |
