1) Post-peak unloading of the confining pressure
峰后卸除围压
2) post-peak unloading confining pressure
峰后卸围压
1.
The tests of conventional triaxial, pre-peak unloading confining pressure and post-peak unloading confining pressure are done to the Baishan marble which comes from access tunnel in Jinping Hydropower Station lying on Yalong River.
对取自位于雅砻江上的锦屏二级水电站辅助洞内的白山组大理岩进行了常规三轴试验和峰前、峰后卸围压试验,通过对试验曲线和岩样破坏特征的分析表明:无论是峰前还是峰后卸围压,岩样都表现出脆性破坏的特征,而岩样破坏表现出的脆性峰前卸围压比峰后卸围压更为强烈;岩样在加、卸载条件下的变形均随主应力差的增大而增大,但在相同的主应力差下,卸载产生的扩容量比加载的扩容量更大;峰前卸围压试验当围压卸到初始围压值的60%左右时,岩样发生破坏;峰后卸围压试验当围压卸到初始围压值的80%左右时,岩样发生破坏。
3) unloading confining pressure at the pre-peak and post peak
峰前、峰后卸围压
4) unloading confining pressure at the pre-peak and post-peak

5) pre-peak unloading confining pressure
