基于极限平衡分析的圆形浅基础破碎岩体地基承载力理论解
Theoretical solution of bearing capacity of shallow circular broken rock -mass foundation according to limit equilibriu m analysis
摘要
Abstract
According to the symmetry of the load and the shape of foundation,the broken rock -mass foundation failure mode should be in the form of double sides shear failure,and each side of the damaged area can be divid-ed into three zones,including the active zone,the transition zone and the passive zone.The passive zone,the theoretical solution of bearing capacity of shallow circular broken rock -mass foundation can be solved combined with static equilibrium conditions as well as considering the shape and size of foundations.Compared with the theoretical solution of BELL formula,the theoretical solution can be proved correctly and practically.Theoretical formula of solution is brief,which will provide a new approach for determination of bearing capacity of broken rock -mass foundation.关键词
