摘　　要：在总结岩石点荷载强度试验的基础上,为研究不同岩性的岩石点荷载强度指数与标准抗压强度的比值的差异,本文通过对山东海阳核电站一期主厂区沉积岩点荷载试验与标准岩块抗压强度试验成果进行的对比分析,得出沉积岩的各向异性指数,进而指导其在工程实际中的应用。Point load test can determine the point load strength indexes of rock. The result then can be used to sort the rock,distinguish the aeolotropism of rock and calculate the uniaxial compressive strength of rock in the whole yard,with the conversion factor which has been calculated by some point load strength and uniaxial co mpressive strength. With the examples of the first-stage construction nuclear power station in Haiyang of Shandong province,this article has concluded that the conversion factor is different as to the different rocks,and then explained the use of point load test in actual project works.
