摘要
根据工程对岩体稳定性评价的要求,应该模拟不同加载路径的应力状态下的试验条件,以便掌握在该试验条件下岩石所作出的力学响应.通过对锦屏二级水电站大理岩在不同加载路径的三轴试验,分析了大理岩在不同应力路径下的能量释放规律和破坏特征.
According to require of engineering to evaluation of rock stability,tests conditions under different loading paths should be imitated,so that to grasp the rock mechanics respond under this test condition.The test data of tri-axial test of marble from Jinping II hydropower station under different loading paths are presented and the deformation properties and energy release law of marble under different loading paths are analyzed.
