摘　　要：目的用灰色理论的控制方程解决实际工程中围岩稳定性的预测问题.方法对于复杂地质条件和不同施工方法作用的围岩变形现场量测数据,提出了采用灰色系统理论分析判断围岩稳定性的控制方程.结果通过灰色线性回归组合模型的分析,建立了描述围岩变形的位移、速率以及加速率的灰色控制方程,并以沪昆铁路客运专线贵州段刘家庄隧道监控量测数据为实例,运用灰色控制方程判断围岩的稳定性并进行稳定性预报.结论在围岩稳定性预测中,灰色控制方程具有较好的适用性,可以较准确的预测围岩变形,确保工程安全.In view of the problems predicting the stability of surrounding rock in underground engineering, the control equations are established based on grey theory to effectively solve the forecasting problem of the stability of surrounding rock in practical engineering. Based on the complex geological conditions and differ- ent construction methods of measurement data in surrounding rock deformation field, the gray control equa- tions to judge the stability of surrounding rock with the grey system theory is proposed. Through the combi- nation of gray linear regression model analysis, set up the gray control equations to describe the deformation of surrounding rock displacement, velocity and acceleration rate ,judge the stability of surrounding rock with the grey control equations based on measurement data of Shanghai-Kunming passenger dedicated line in GuiZhou LiuJiaZhuang tunnel, and make a prediction. Gray control equations have a good applicability in predicting the stability of surrounding rock, they can more accurately predict the deformation and guarantee the engineering safety.
