某高层商住楼混凝土柱及剪力墙分批置换技术方案与应用

Technical scheme and application of batch replacement of concrete columns and shear walls in a high-rise commercial and residential building

混凝土置换是一种适合处理存在混凝土强度严重偏低或有严重缺陷受压构件可行有效的加固方法,本文通过某高层商住楼四层柱及剪力墙混凝土强度严重偏低的工程实例,详细介绍和阐述分批置换技术及具体应用,可为同类工程问题的处理提供参考。

Concrete replacement is a feasible and effective reinforcement method for compressive members with serious low concrete strength or serious defects.This paper introduces and expounds the batch replacement technology and its application in detail through an engineering example of a high-rise commercial and residential building with four-storey columns and shear wall with serious low concrete strength,which can provide reference for the treatment of similar engineering problems.
