摘要
结合上海市某工程的实际情况,通过对灌注桩后注浆技术工艺原理的分析,比选出适用于软土地基的后注浆施工方法,并在工程实践中应用验证,确定了后注浆施工参数,最终桩基承载力试验一次性合格,为工程的顺利实施提供了条件,对软土地基钻孔灌注桩后注浆施工具有一定的借鉴意义。
Based on the actual situation of a certain project in Shanghai,through the analysis of the principle of post-grouting technology,the post-grouting construction method suitable for soft-soil foundation is selected and verified in engineering practice.Grouting construction parameters,the final pile foundation bearing capacity test is qualified once,which provides conditions for the smooth implementation of the project,and has certain reference significance for post-grouting construction of cast-in-place piles in soft soil foundation.
