无锡地铁3号线一期工程技术创新与应用

Technical Innovation and Application of Wuxi Metro Line 3 Phase I Project

文章以无锡地铁3号线一期工程为背景,重点阐述了承压富水复合地层盾构智能掘进成套技术、顶管法施工联络通道技术、高承压水头条件下低净空拔桩技术、车辆段减振降噪综合技术、轨道交通安全通信网络节能覆盖技术及应用等。在项目建设期间,获得多项省部级及国家级奖项,并成功获得第二十届中国土木工程詹天佑奖。

The paper takes the first phase of Wuxi Metro Line 3 project as the engineering background,focusing on the intelligent excavation technology of shield tunneling in pressure rich water composite strata,the technology of top pipe method construction connection channel,the low clearance pile pulling technology under high pressure head conditions,the comprehensive technology of vibration reduction and noise reduction in the vehicle depot,and the creation of energy-saving coverage technology and application for rail transit safety communication network.During the construction period of the project,we won multiple provincial,ministerial,and national awards,and successfully won the 20th Tien-yow Jeme Civil Engineering Prize.
