Abstract: Deformation of surrounding rock of underground powerhouse with nonlinear characteristics is the reflect of various factors of hydropower station system. According to the deformation monitoring data of surrounding rock of Taian underground powerhouse,the rate of deformation is considered as a series of special solution of the nonlinear dynamic model,and then to inverse the nonlinear dynamic model. Using catastrophe theory,the cusp catastrophic model of surrounding rock deformation rate is established,and the stability of the surrounding rock is analyzed,and then the instability process of surrounding rock is further revealed. Study shows that the surrounding rock of Taian underground powerhouse is stable,and the result is consistent with the numerical calculation. It shows that this method is reasonable and effective,and provides a reference for similar projects.
