谈顶升在已有建筑双向纠倾中的应用

Application of Jacking in Bidirectional Rectification of Existing Buildings

以镇江某项目的顶升纠倾为例,介绍了顶升纠倾的基本原理。并结合该工程现场施工资料及后期的裂缝、沉降观测报告,表明采用先基础加固后双向调整顶升纠倾不仅能够满足建筑物的使用性、安全性,而且具有良好的社会效益与经济效益。

Taking the jacking rectification of a project in Zhenjiang as an example,this paper introduces the basic principle of jacking rectification.Combined with the construction data of the project site and the observation reports of cracks and settlement in the later period,it is shown that the adoption of foundation reinforcement before bidirectional adjustment of jacking rectification not only can satisfiy the usability and safety of the building,but also has better social and economic benefits.
