摘要: 在天津盘山地区某项目中,对强风化花岗岩进行了点荷载及单轴抗压强度试验。本研究通过两种试验的对比,对强风化花岗岩点荷载试验的计算参数及相关特征进行初步研究,发现了对强风化花岗岩规范方法计算点荷载试验强度与实际单轴抗压强度的区别,并由该关系曲线总结了通过点荷载试验计算单轴抗压强度的公式。

Abstract: Both the point load and the uniaxial compressive tests are conducted on the strongly weathered granite rock samples from a project site in Panshan District, Tianjin City. The parameters in calculating the point load strength are studied in the tests. The method in the current design code of estimating the uniaxial compressive strength from the point load values is discussed and the correlations between the point load test results and the uniaxial compressive strength values are developed.
