Research on key construction technology of subway station deep foundation pit adjacent to shallow foundation building in complex stratum——Taking Tiaoxi station of SGJC-1 section of Hangzhou airport rail express as an example

针对复杂地层邻近浅基础建筑物地铁车站深基坑施工,本文结合杭州机场轨道快线SGJC-1标苕溪站为例,在车站深基坑变形控制、深基坑周边建筑物变形控制和基坑施工全过程管线变形控制等施工关键技术方面进行了研究分析。结果表明,围护结构变形、建筑物变形和管线变形均在规范允许范围内。

Aiming at the deep foundation pit construction of subway station adjacent to shallow foundation building in complex stratum, this paper takes Tiaoxi station of SGJC-1 bid of Hangzhou airport rail express as an example, and analyzes the key construction technologies, such as deformation control of deep foundation pit, deformation control of buildings around deep foundation pit and deformation control of pipelines in the whole process of foundation pit construction. The results show that the deformation of envelope, building and pipeline are within the allowable range.
