Laws of surrounding rock deformation of soft rock roadway in sea area

Mechanical characteristics of surrounding rock of soft rock roadways in the sea area are obtained by tests. The characteristic of the soft rocks are summarized on the basis of test results. Three typical deformation curves of destructive curve, rheological curve and stable curve are concluded by analyzing deformation and failure characteristics. The research simulates the rehelogic process of the deformation of the surrounding rock by using viscous model in FLAC3D and compares the simulated rhelogic curves with the curve obtained from in-situ measurement. The results show that viscous model can simulate rheological process of roadways perfectly.
