根据基础及荷载的对称性，将破碎岩体地基的破坏模式确定为双侧剪切破坏，破坏区分为主动区、过渡区和被动区3个部分，根据极限平衡分析，采用静力平衡分析的方法，并考虑基础形状尺寸、埋深、地基黏聚力、重度等因素对地基承载力的影响，推导出圆形浅基础破碎岩体地基承载力的理论解。通过与 BELL 经典公式进行对比，证明了理论解的正确性和实用性。破碎岩体地基承载力的理论解理论推导清晰，结论公式简单，为圆形浅基础破碎岩体地基承载力的确定提供一种新途径。

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.
