Abstract

Based on theory of the limit equilibrium and FLAC3D numerical simulation, optimization analysis on the support of 3401 gate road in Sanhekou food mineral substance base. Optimization processes are mainly to make numerically simulate about non-supporting state, the original state support and optimized supporting design three conditions, getting the change of the stress fields, the displacement fields and the plastic zone. The results showed that the optimized supporting design can better control the deformation of surrounding food and stress distribution. Meanwhile, the ground pressure monitoring on the scene can also verify the rationality of the optimized supporting design. It provides Sanhekou food mineral substance base and other similar food mineral substance bases theoretical and applied guidance.
