Topology Optimization for Excavation of Road Tunnel

Topology optimization is high level optimization method of structural optimization,which is a hotspot study of engineering field.But there is not research achievement for topology optimization of tunnel engineering.The system of tunnel optimization is established perfectly by refers to the method of topology optimization.Taking area of disturbance as area of topology optimization and boundary of disturbance area as boundary of topology optimization area,the method of topology optimization theory with elasto-plastic FEM is applied.With the analysis of different vary procedures of excavation,reinforce place in the area of disturbance is found.This research result,in addition to the method applied in it,thus,can be used as reference in the construction and design of road tunnel.
