浅谈广州某项目逆作法设计与施工管控要点

Discussion on the Inverse Method Design and Construction Control Key Points of a Project in Guangzhou

本文旨在通过项目逆作法设计施工实例,地下地上双向施工的全逆作法,对工程逆作法施工方法选择、总体部署与难点、特点,以及地下连续墙、竖向支撑桩柱、降水、土方开挖的受力体系转换等各个关键施工技术攻关与成果进行详细阐述。分别从设计角度、工程角度出发对其所需配合逆作法进行调整的核心事项、关键工艺、施工功效等问题进行归纳总结,为后续项目采用逆作法的决策提供技术依据以及数据支持。

This article aims to through the inverse method for example of project design and construction and fully inverse method for two-way construction of underground-aboveground,the engineering construction method selection,overall deployment and difficulties,characteristics,and underground continuous wall,vertical support pile,precipitation,earth excavation stress system transformation of the key construction technology research and achievements were elaborated in detail.From the perspective of design and engineering,the core matters,key processes,construction efficacy and other issues required to be adjusted with the inverse method are summarized respectively,so as to provide technical basis and data support for the decision of the reverse project.
