植筋技术在地基基础加固改造工程中的应用

Application of Embedded Steel Bar in Foundation Reinforcement and Reconstruction Engineering

对植筋连接新旧混凝土结合面抗剪承载力研究现状进行了分析,结合工程实例,探讨其在地基基础加固改造中的应用。在确定结合面抗剪承载力时可参考现有研究成果和国外相应规范,选择适合的理论公式,在承载力计算和构造要求的综合控制下进行植筋设计,并留有适当的富余量,以保证结构安全。

This article analyzes the current research of the shear bearing capacity of bonding interface between new and old concrete with embedded steel bars,and combine the project cases to discuss the application in strengthening and renovation of the foundation.Current research achievement and foreign relevant code can be consulted and applicable formula can be selected in calculating the shear bearing capacity of interface between new and old concrete.To design the embedded steel bar with the combination of bearing capacity calculation and structure requrement,and get suitable reservation can ensure the structure.
