摘　　要：我国工程界对岩石地基承载力问题有不同认识,作者就其中的一些重要问题提出了自己的看法。包括Mohr-Coulomb准则是否适用于岩石地基?可否用抗剪强度指标计算岩石地基承载力?用单轴抗压强度指标确定岩石地基承载力是否合理?岩石地基承载力是否可做深宽修正?怎样看待岩石地基承载力的理论计算和经验方法估计?并对用剪切波速进行岩土分级和承载力估计、地基承载力的综合判断问题提出了看法。There is different understanding on the bearing capacity of rock foundation in our engineering field. Some opinions on the issues are presented by the author, which include whether Mohr-Coulomb criterion is fit for rock foundation？ whether the indices of shear strength can be used to calculate the bearing capacity of rock foundation？ whether it is reasonable to determine the bearing capacity with the indices of shear strength from uniaxial compression tests？ whether the bearing capacity can be modified with the depth and width？ and how to treat the theoretical calculating and the experience estimation for the bearing capacity of rock foundation. Some views on the comprehensive judgments of the rock classification and the bearing capacity are put forward.
