摘要地下厂房围岩变形具有非线性特点，是水电站系统多种影响因素作用的直观反映。基于泰安电站地下厂房围岩变形监测数据，将变形速率作为非线性动力模型一系列特解，反演出非线性动力模型；运用突变理论，建立围岩变形速率尖点突变模型，分析围岩的稳定性，同时进一步揭示围岩失稳过程。研究结果表明，该水电站地下厂房围岩处于稳定状态，与数值计算结果一致，说明该方法合理有效，可为同类工程提供一定参考。

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.
