摘　　要：岩体所处应力状态不同 ,其强度特性则有异。参考Serrano的研究成果 ,以水平承载面均质岩基为例 ,在介绍岩体性质转变时Hoek -Brown强度包线形状、转变点应力、滑移线应力特征的基础上 ,阐述了高应力状态下水平均质岩基极限承载力的求解方法。最后 。On the basis of Serrano' work,the authors introduce the character of Hoek-Brown strenth envelop and characteristic line,and the method determining ultimate bearing capacity under high stress condition with characteristic theory expressed with Hoek-Brown criterion.In order to explain the method,an example is offered in this paper.It is shown that,high stress condition is not often occurred in civil engineering.
