摘要
分析了小变形力学理论在分析软岩工程大变形时存在的问题,指出在研究软岩工程大变形问题时应该采用大变形力学理论,并给出了非线性大变形数值方法在软岩巷道工程中的应用实例。
It is unreasonable to study the large deformation of soft rock with classic linear deformation theory. In this paper it is stated that the right analysis way of soft rock large deformation should use the finite deformation mechanics. Based on the finite deformation mechanics, an engineering case analysis is given to simulate the failure mechanism and the process of large deformation of the soft surrounding rock of the roadway by using FLAC technique.
