盾构机及后配套过运营高铁站施工技术

The Construction Technology of Shield Machine and Affiliated Complete Passing-through Operating High-speed Rail Station

盾构机在完成一个区间的掘进后,直接通过主体结构已完成的车站,是现代城市地铁建设的常见施工工法,既减少了盾构到达、解体、吊运和再安装施工工序,又极大地降低了工程风险,缩短了工期。以合肥地铁四号线三标盾构施工为例,介绍盾构机及后配套站内过站的施工方法和快速过运营高铁站施工技术,并对其效益对比、风险进行了分析。

It is a common construction method in the modern urban subway construction, that the shield machine directly passes through the station, whose main structure has been completed after tunneling in a section. It not only reduces the construction procedures of shield arrival, disintegration, lifting and re-installation, but also greatly reduces the project risks and saves the construction period. Taking the shield construction of Hefei Metro Line 4 as an example, this paper introduces the construction method of shield machine and its supporting station and the construction technology of fast passing high-speed railway station, and analyses its benefit comparison and risks.
