摘要
逆作法是近年来发展起来的广泛应用于高层建筑深基础施工中的一种新兴的施工工艺。由于采用地下连续墙或排桩作为基坑的支护体系同时也可作为地下结构外墙,采用地下结构的各层楼板作为支护体系的支撑,在实际施工过程中支撑桩与柱、支撑柱与梁板、梁板与地墙间的节点处理往往成为施工难题。作者通过工程实例,介绍了多种运用于高层建筑深基础逆作法施工中的节点处理方法,使结构节点变得简单、实用、有效。
The top-down construction method is a rapidly developing construction technology used in the deep foundation of high-rise buildings. As the diaphragm wall or the row of piles can act as both the basement wall and the supporting system, and the bracings are the floor slabs underground, the joint nodes of pile and column, column and slab, slab and diaphragm are usually difficult to deal with. In this article, some practical and effective joint nodes are introduced through some practical projects.
