杭州解放路延伸线新城隧道采用左、右线双洞分修型式，具有埋深浅、跨度大、间距小的特点，穿越地层地质差，同时需下穿既有沪杭铁路线，施工技术含量极高。文章介绍了穿越铁路段施工中采用的综合技术及相应的针对性辅助施工措施，结合监测信息反馈，分析阐释了浅埋暗挖法及其综合配套技术在施工实际中的成功应用，具有重要的现实意义。

Xincheng tunnel on Hangzhou Jiefang Road extending highway is a twintube tunnel that is supershallowburied, largespanned and closespaced, as well as running within poor geological conditions and underneath existing ShanghaiHangzhou railway, therefore the construction of the tunnel contains extremely advanced technology. The article introduces the comprehensive technology and the corresponding assistant measures adopted during the construction of the tunnel underneath the railway. Furthermore, by means of feedback of the monitoring results, the article analyses and explains the successful application of shallowburied undermining method and its comprehensive assistant technology in the tunnel construction, which  has important practical significance.
