复杂条件下重载钢便桥设计与施工技术分析

Design and Construction Technology Analysis of Heavy Load Steel Temporary Bridge Under Complex Conditions

施工便桥是一种为工程施工和运输需要而修建的临时性桥梁。结合嘉松公路越江新建工程施工进场道路受阻的实际情况,经方案比选采用型钢便桥,以保证施工所需材料构件及设备顺利进场。阐述了复杂施工条件下施工便桥方案的选取原则,介绍了便桥的设计思路及施工要点。

Temporary bridge for construction is a kind of temporary bridge built for engineering construction and transportation.Combined with the actual situation that the construction access road of Jiasong Highway New River-crossing Project is blocked,the section steel temporary bridge is adopted through scheme comparison to ensure the smooth access of materials,components and equipment required for construction.This paper expounds the principles of selecting the schemes of the temporary bridge under the complicated construction conditions,and introduces the design ideas and construction points of the temporary bridge.
