沪宁高速公路扩建工程以路基两侧拼接加宽为主,由原来的四车道对称拓宽为八车道,拼接部分以路基沉降控制为主要控制对象。介绍沪宁高速公路扩建工程(苏州段)软土地基的工程特性及扩建工程路基施工控制的特殊性;介绍控沉预应力管桩在沪宁高速公路扩建工程复合地基处理中的施工可行性及施工技术。
Shanghai-Nanjing Expressway expansion project to splicing on both sides of the roadbed widening mainly from the original four-lane symmetrical broaden to eight lanes, splicing part of subgrade settlement control as the main control object. This paper introduces the engineering characteristics of soft soil foundation of Shanghai-Nanjing Expressway expansion project (Suzhou section) and the particularity of subgrade construction control in extension project. It also introduces the feasibility of construction of pre-stressed pipe pile in the treatment of composite foundation of Shanghai- Nanjing- Construction Technology.
