Study Of Floor Heave Mechanism In Deep Soft Rock Roadway

Flac3D is utilized to study floor heave mechanism and propose corresponding solving method of floor bolt-grouting in roadways under 550m in Longmei company. In addition, Flac3D can perform the simulation of stress field and displacement field and plastic zone in order to improve rationality of the scheme. It has been proved by practical project that this proposal efficiently limits the deformation of floor heave in deep soft roadways.
