摘要
随着城市建设的不断推进,我国道路交通建设工程中面临新建线路与既有线路立体穿叉,修建地下道路是一种有效途径。地下隧道的施工方法有很多,管幕箱涵法是近几年来新兴的一种施工方法,其将管幕法和箱涵法结合起来,达到很好效果,特别是在我国软土地区适用性较强。现以上海市田林路下穿中环线地道工程为例,结合北虹路地道工程对该工程的技术难点进行分析,提出可靠的技术保障措施。
With the continuous progress of urban construction,China's road traffic construction projects are facing three-dimensional cross-cutting problems of new and existing lines,so construction of underground roads is an effective way. There are many construction methods for underground tunnels. Pipe curtain-box culvert method is a new construction method in recent years. It combines pipe curtain method with box culvert method to achieve very good results. Especially in China's soft soil area the applicability is strong. Taking the project of Tianlin Rd. underneath Mid-ring Rd. tunnel in Shanghai as an example,this paper analyzes the technical difficulties of the project,and puts forward the reliable technical safeguard measures.
