摘　　要：考虑岩体非线性破坏特征并基于岩基分类,将经典地基承载力计算理论与经验岩体强度准则结合,近似推求了由Hoek-Brown准则确定剪切破坏模式下均质岩基极限承载力的Bell解,并以工程算例对其计算步骤进行说明。Shear failure is the commonest failure,which often takes place in sound,jointed and weak rock foundation. On the basis of inferring shear parameters of rockmasse with Hoek-Brown strength criterion,the Bell solution is introduced to determine ultimate bearing capacity of homogeneous rock foundation under shear failure,and the method validity is analyzed.
