摘　　要：根据洞室围岩的变形特征,同时考虑了岩石材料的流变特性、开挖过程中的时空效应以及地下水影响,利用数理统计中的非线性模型,找出相关变量之间的表达式,建立了围岩变形的非线性回归模型,并将其用于工程实践,结果表明,该模型具有较高的可信度.According to the characteristics of surrounding rock deformation of caverns, and in consideration of the rheological property of rock materials, the spacetime effect during cavern excavation, and the influences of groundwater, the nonlinear model in mathematical statistics was adopted to find the relationships between some relevant variables, and a nonlinear regression model for surrounding rock deformation was developed. The application of the model to practice shows that the model is of high reliability.
