Design of Fabricated Concrete Structural Utility Tunnel Bridge

摘要:

在钢箱梁的荷载试验中，利用梁格法建模分析与实测试验结果进行对比，通过两者在不同荷载试验工况下的挠度和应变的变化趋势和结构振型，分析梁格法在该结构下的可行性。结果表明，在静载试验中两种曲线的趋势基本相同，在动载试验中两种振型基本相似，说明梁格法具有较高的实用性和准确性。

Abstract:

Based on an engineering case, the structural style of fabricated concrete utility tunnel bridge is put forward. Aiming at its stress characteristics and considering the construction requirements, the section is adjusted on the basis of utility tunnel and the design section of this utility tunnel bridge is derived. Starting from the solid element analysis of finite element, the buckling stability and mechanical properties of fabricated concrete utility tunnel bridge are specially studied, and the vertical and horizontal calculations of the structure are carried out. Combined with this project, some design suggestions are given. The study conclusion and suggestions can provide the reference for the design of the similar projects.
