Based on the Design and Analysis of the Mechanical Characteristics of the 3D3S Bailey Beam Steel Trestle Structure
It is of great significance to analyze the stress characteristics of the steel trestle structure to ensure the safety of the steel trestle.In this paper,the 3D3S structural analysis so ftware of Tongji University is used to establish a three-dimensional model of the steel trestle,and the two load cases are considered to analyze the force of the bridge deck beam,Bailey beam,load-bearing beam,steel pipe pile and other structures of the steel trestle,and the results show that,nder the two load conditions designed in this paper,the bridge deck beam,Bailey beam,load-bearing beam and steel pipe pile of the steel trestle meet the design requirements;under different stratum conditions,the steel pipe pile has different minimum soil depths,so as to avoid the steel pipe pile piling according to a uniform depth.
