后压浆对桩端承载力及桩侧阻力增强的分析

Analysis of the Enhancement of Pile Bearing Capacity and Pile Side Resistance by Post Grouting

近年来,后压浆技术的推广和应用在不断扩大,并在很大程度上获得了经济效益及社会效益。基于此,论文对后压浆在桩端承载力以及桩侧阻力增强的机理进行了概述,并结合工程实例,对其原因进行了分析,希望为本地区相关工程在应用后压浆技术时,提供参考和借鉴。

In recent years, the popularization and application of post grouting technology have been expanding, and to a large extent, it has achieved economic and social benefits. Based on this, the enhancement mechanism of the bearing capacityat the pile end and the increase of pile side resistance bythe post grouting technologyis summarized, and the reasons are analyzed with the engineering example. It is hoped to provide reference for the related engineeringin the application ofpost groutingtechnologyin the local area.
