逆作法施工在城市地下空间开发中的应用

Application of Reverse Construction Method in Urban Underground Space Development

逆作法施工具有缩短工期,节约工程造价,对周围环境的影响小的优点。在城市高层建筑深基坑支护施工的开发和应用中有着广泛的应用前景。初步工程实践表明,采用逆方法构造城市地下结构具有良好的经济效益和社会效益。介绍施工技术原则、施工关键技术及应用建议。

Reverse construction has the advantages of shortening the construction period, saving engineering cost and having little impact on the surrounding environment. It has broad application prospects in the development and application of deep foundation pit support construction for urban high-rise buildings. Preliminary engineering practice shows that using the inverse method to construct urban underground structures has good economic and social benefits. The article will focus on construction technology principles, key construction techniques and application recommendations.
