摘要
针对岩石地基岩体固有特性，在系统分析岩基承载力影响因素、岩石地基的破坏模式的基础上，对当前工程界确定岩石地基承载力的方法给予评述，并对工程中岩石地基承载力确定问题提出以下建议：充分发挥规范的作用，特别是岩石单轴抗压强度确定岩石地基承载力的方法，对折减系数要进一步的完善；加强岩石地基承载力计算理论的研究，建议按照岩石地基的影响因素综合分析确定其破坏模式，按照不同破坏模式确定计算公式；充分发挥数值模拟的优势，在模型和参数两方面做到准确可靠，使其更好地应用于岩石地基承载力的确定。
On the basis of analyzing the factors influencing the bearing capacity and the failure models of foundation ,the authors evaluate the present methods used to determine the bearing capacity of rock foundation in engineering,and give some advice：Exerting the function of the criterion best, especially the method of the single stalk in rock anti - presses in ascertaining bearing capacity of rock foundation, making the fold - coefficient to be further perfect; enhancing the theoretical research in calculation on bearing capacity of rock foundation; suggesting to establish its breakage mode according to the influence factor of the rock foundation behind synthesized analysis; using different calculation formula according to breakage mode;making the best use of the advantages of number simulate ; making sure the parameter and model are accurate and dependable so that the number simulate will be better used in ascertaining the bearing capacity of rock foundation.
