Finite Element Simulation Analysis of Separate Overpass Structure

摘要

Overpass is the important part of urban transportation infrastructure. This paper adopts finite element method to carry out three-dimensional finite element simulation analysis for Longhai railway separate overpass. Researching variation law of the overpass's stress and displacement in construction process and operating process. Analysis results show that, structure of Longhai railway separate overpass is reasonable, force of overpass structure is explicit, it meets the requirements for engineering.
