岩石地基承载力，是地基稳定性分析中的强度问题，不仅控制建筑物的安全，而且客观上影响工程的经济合理性，因此，精确确定岩基承载力至关重要。介绍基于Ｈｏｅｋ Ｂｒｏｗ ｎ 强度准则计算完整岩体、节理岩体、破碎岩体、软弱岩体岩基承载力的极限平衡解法，以及参数ｍ ，ｓ的确定方法。最后，以工程实例证明此方法的正确性和实用性。
The bearing capacity of rock foundation is the strength problem in foundation stability analysis. It not only controls the safety of the building, but also objectively affects the economic rationality of the project. Therefore, it is very important to accurately determine the bearing capacity of the rock foundation. This paper introduces the limit equilibrium method for calculating the bearing capacity of intact rock mass, jointed rock mass, fractured rock mass and soft rock mass based on Hoek Brow n strength criterion, and the determination method of parameters m and s. Finally, an engineering example is used to prove the correctness and practicality of this method.
