钻孔灌注桩后注浆承载力分析及在煤炭工程中的应用

Later Bearing Capacity Analysis of Bored Piles and Its Application in Coal Engineering

针对我国原煤及产品煤存储量大的现状,文章对煤炭行业中钻孔灌注桩的后注浆的承载力进行了数值分析研究,提出提高钻孔灌注桩的后注浆承载能力方法和使桩基形变减小的原理,并对干扰灌注桩承载能力的因素做了分析,提出桩底后注浆技术的解决方案,煤炭工程实例的引入论证了设计方案的正确性和有效性。

Direct to the sate of China＇s raw coal and product coal storage.In this paper,makes numerical analysis on the bearing capacity of bored pile,proposes methods to increase the bored piles bearing capacity and principles to reduce pile deformation,analyzes the interference factors to pile bearing capacity,the solutions of later grouting technology,and introduced project examples demonstrate the correctness and effectiveness of the design scheme.
