道路上跨对既有地下结构影响的分析与评价

Analysis and evaluation on the influence of road span to the existed underground structure

新建道路上跨既有地下建筑结构时,按规范需要对被跨越工程进行涉路项目工程技术评价。结合案例,从新建道路上跨既有地下建筑结构的设计、施工、运营全过程,按不同工况分析最不利情况对地下结构进行分析与评价,为其他类似工程提供借鉴。

When a new road crosses an existed underground building structure,it is necessary to carry out engineering technical evaluation of the crossing project according to the requirements of the code.Combined with the case,from the design,construction and operation process of the new road spanning the existed underground building structure,the paper analyzes the most unfavorable situation according to different working conditions,analyzes and evaluates the underground structure,so as to provide reference for other similar projects.
