摘　　要：点荷载强度试验是一种可以代替单轴抗压强度试验进行岩石强度预测的行之有效的方法,两者之间存在包括但不限于线性关系的相互关系。通过收集以往工程岩石点荷载强度与单轴抗压强度试验数据,分析数据的可靠性,利用不同岩石类别修正后的点荷载强度与岩石单轴抗压强度的平均值进行数值拟合,得到两者之间的经验关系表达式,为输变电工程岩石单轴抗压强度的预测提供更为可行可靠的依据。The point load strength test is an effective method to replace the uniaxial compressive strength test for rock strength prediction.There is a relationship between the two,including but not limited to the linear relationship.In this paper,the reliability of the data is analyzed by collecting the data of point load strength and uniaxial compressive strength test in the past,and the empirical relationship between the two is obtained by using the modified point load strength of different rock types and the average value of uniaxial compressive strength of rock.The expression provides a more feasible and reliable basis for the prediction of uniaxial compressive strength of rock in power transmission and transformation projects.
