摘　　要：以支井河特大桥锚碇区岩体为试验对象,进行了岩石力学性质试验,包括单轴压缩强度试验、单轴压缩变形、三轴应力应变全过程试验、结构面剪切试验,并对试验结果进行了分析,从而为整个山体稳定性评价提供了依据。Mechanical properies of rock mass is analyzed by mechanical tests. The tests include uni-compression strength test, uni-compression deformation test, trixlal compression test and shear test of discontinual plane. The test results are analyzed. The results are very significant to appreciating the stability of rock mass.
