不同建设条件下的常规桥涵设计分析

Design Analysis of Conventional Bridges and Culverts under Different Construction Conditions

随着我国公路事业的迅猛发展,桥梁建设也不断发展,成为公路建设不可缺少的一部分。目前公路建设中桥梁结构仍以常规跨径混凝土结构为主,文章从常规桥涵设计初期外业调查、内业设计及施工期间后续服务方面,探讨了不同建设条件下常规桥涵设计中应重点关注的内容和存在的问题,并总结个别典型问题的解决方案,可为今后的公路桥涵设计工作提供参考。

With the rapid development of China’s highway industry,bridge construction is also developing continuously,becoming an indispensable part of highway construction.At present,the bridge structure in highway construction is still dominated by conventional span concrete structures.This paper discusses the contents and problems that should be paid attention to in the design of conventional bridges and culverts under different construction conditions from the aspects of field investigation,internal design at the initial stage and follow-up service during construction,and summarizes the solutions to individual typical problems,which can provide references for highway bridge and culvert design in the future.
