相对于常规“大开挖”的“正作法”而言,逆作法一项近几年发展起来新兴的基坑支护施工技术,是高层建筑物目前最先进的施工技术方法。实践证明,利用集传统逆作法和地下连续墙的“两墙合一”工艺为一身的新型逆作法工艺施工创造了良好的经济效益和社会效益。 In contrast to the conventional method of normal excavation, a new approach to supporting the construction of foundation pit, which has been developed in recent years, is the most advanced construction technology method for high-rise buildings. Practice has proved that the use of traditional reverse method and underground continuous wall “two walls together ” technology as a whole new method of reverse construction process has created good economic and social benefits.
