The in - situ stress in the slope is measured through relieving stress by overcoring . then the analysis that in - situ stress in slop influences the development and stability of dangerous rock is carried on by fracture mechanics . water pressure includes hydrostatic pressure and hydrodynamic pressure 通过对洪崖洞现场地应力的套孔应力解除，测试了危岩边坡的残余地应力，运用断裂力学的方法分析了地应力对危岩发育和对现有危岩稳定性的影响。
