摘要
钻孔灌注桩是一种常见的基桩型式,在工业与民用建筑、桥梁、电力、市政等工程中具有广泛的应用.灌注桩按照成桩方法可分为干作业法、泥浆护壁法、套管护壁法钻(挖)孔灌注桩以及长螺旋压灌灌注桩等.实际工程中,无论采用哪种成桩方式,都可能存在质量问题.论文以实际项目为依托,进行了灌注桩承载力补强技术的应用研究,为同类桩基工程问题处理的技术实践和理论研究提供了参考.
Abstract
Drilled pile is a common type of foundation pile,which has a wide range of applications in industrial and civil construction,bridges,power,municipal engineering,and other projects.Grouting piles can be divided into dry operation method,mud wall protection method,casing wall protection method for drilling(digging)hole grouting piles,and long spiral pressure grouting piles according to the pile formation method.In practical engineering,regardless of the pile forming method used,there may be quality issues.This article is based on practical projects and conducts research on the application of reinforcement technology for bearing capacity of cast-in-place piles,providing reference for technical practice and theoretical research on similar pile foundation engineering problems.
