摘要依据监测位移，基于突变理论，提出快速、简便评判围岩稳定的新方法和量化标准。建立非线性动力–尖点突变模型，根据突变的失稳判据(突变特征值D≤0)，计算出突变位移速率；依据稳定判据(突变特征值D＞0)确定稳定位移速率，并计算位移速率比值。根据该方法，提出主厂房(或主变室)评判量化标准：稳定位移速率为0.4 mm/d(或0.2 mm/d)，突变位移速率为9.0 mm/d(或2.5 mm/d)，位移速率比值为18%(或14%)。并将此方法应用于大型工程围岩稳定性评判，验证评判方法和量化标准的合理性和有效性，可为同类工程提供参考。

Abstract：Based on monitoring displacement and catastrophe theory，a new rapid and simply quantitative criterion is proposed to assess the stability of surrounding rock. The nonlinear dynamic-cusp catastrophe model is established. According to the instability catastrophe criterion(catastrophe feature value D≤0)，catastrophe displacement rate is calculated. The stable displacement rate is determined and the ratio of displacement rate is calculated by using stability criterion(D＞0). According to the method，the judgment quantitative criterion for main power house (or main-transformed cavern) is put forward，which is that the stability displacement rate，catastrophe displacement rate and the ratio of displacement rate are 0.4(or 0.2) mm/d，9.0(or 2.5) mm/d and 18%(or 14%)，respectively. The judgment quantitative criterion is applied to assess the surrounding rock stability of large-scale project. The rationality and effectiveness of the judgment method and quantitative criterion are validated，which can provide reference for the similar project.
