| 摘 要： | 岩石点荷载强度试验可以求得岩石点荷载强度指数，由强度指数与抗压强度之间的关系可以换算出岩石的单轴抗压强度，进而可计算出岩基承载力，通过工程实例，介绍了点荷载试验评价人工挖孔桩底岩基强度和承载力的方法，并与岩基载荷试验结果进行了对比。

| Abstract: | Point load test can determine the point load strength indexes of rock. The result then can be used to calculate the uniaxial compressive strength of rock,from which the bearing capacity of rock foundation can be decided. With the examples,this article introduced the method of point load for the evaluation of strength and bearing capacity of rock foundation in the artificially excavated holes for piles,and compared the results with those of load test of rock foundation. |
