注浆加固在填土地基中适用性和要点的探讨

Discussion on applicability and key points of grouting reinforcement in filling foundation

本文以采用注浆加固处理的某建筑场地基础为例,分析了浅部土层的分布情况和工程特性、地下水位情况等注浆条件,并根据注浆加固后地坪的沉降观测成果对场地内成分有差异填土层的注浆效果进行了分析统计。总结出注浆加固处理方法对性质不同的填土层的适宜性,并对注浆加固岩土勘察和地基检测的要点进行了建议,为注浆加固地基基础的安全性提供依据。

Taking the foundation of a building site reinforced by grouting as an example,this paper analyzes comprehensively the distribution of shallow soil layer,engineering characteristics,groundwater level and other grouting conditions.According to the observation results of ground subsidence after grouting reinforcement,the grouting effects of filling soil layer with different components in the site are analyzed and counted.This paper summarizes the suitability of the grouting reinforcement method for filling layers with different properties,and puts forward some suggestions on the key points of geotechnical investigation and foundation detection for the grouting reinforcement.
