基坑工程涉及到多学科知识,具有很强的综合性.结合工程勘察得到的综合地质条件和周边环境,对基坑支护进行设计选型和分析,才能得到最适宜的支护方案.文章对存在液化土层的基坑工程进行处理和研究,采用双排灌注桩支护形式,以第10层黏土层作为灌注桩持力层,并分析该支护方案的可靠性,得出该支护方案的边坡整体稳定安全系数和抗倾覆稳定性系数均满足规范要求.
Foundation pit engineering involves multidisciplinary knowledge and is highly comprehensive.Only by combining the comprehensive geological conditions and surrounding environment obtained from the engineering survey and conducting design selection and analysis of the foundation pit support can the most appropriate support plan be obtained.This article processes and studies foundation pit projects with liquefied soil layers,adopts a double-row cast-in-place pile support form,uses the 10th layer of rock and soil as the cast-in-place pile supporting layer,and analyzes the reliability of the support scheme,and concludes The overall stability safety factor and anti-overturning stability factor of this support scheme meet the specification requirements.
