软土地层地铁车站的新型盖挖法施工

软土地区采用标准化、模数化的可回收重复利用临时路面系统和首道支撑采用钢筋混凝土兼作临时路面支承结构的新型盖挖法,在上海轨道交通车站建设中获得成功。还系统研究了临时路面系统、竖向支撑体系、横向支撑体系等关键技术。这种新型盖挖法能够最大限度地减小对地面交通的影响,有极大的推广价值。

A New Type of Cover-cut Method for Construction of Metro Station in Soft Stratum

A new type of cover-cut method is successfully applied to construction of the rail transit station in the soft ground of Shanghai, which uses the standard and modulus recyclable and reusable temporary pavement system in the soft ground area, with the first support of reinforced concrete also for the support structure of the temporary pavement. Some key techniques are studied systematically, such as the temporary pavement system, and vertical and transverse support systems. This new method can minimize the impact on the ground traffic and is of great value for popularization.
