软土地基城市跨河桥涵案例设计分析

Case Design Analysis of Urban River-crossing Bridge and Culvert on Soft Soil Foundation

结合某软土地基城市桥涵工程,通过方案比选,确定了桥涵总体布置方案采用钢筋混凝土箱涵的形式。利用midas软件对结构整体受力进行了计算分析,结果表明:采用劲性体管桩的复合地基方案满足了箱涵对地基承载力要求。本工程案例的设计分析可为类似项目和工程提供参考。

In combination with an urban bridge and culvert project on soft soil foundation,the general layout of bridge and culvert is determined through scheme comparison in the form of reinforced concrete box culvert.The calculation analysis is made on the overall stress of the structure by designing and utilizing Midas software.The results show that the composite foundation scheme of rigid pipe pile meets the requirements of box culvert on the bearing capacity of foundation.The design analysis of this project case can provide reference for similar projects and engineering projects.
