摘　　要：文章以浙江地区某高速公路工程某桥头需要二次开挖回填的路段为例,通过阐述注浆法的基本原理,合理选择注浆孔的间距、压力、注浆量以及具体的沉降观测参数等,为施工提供了有效参考,获得了良好的注浆效果,有效控制了路基不均匀沉降。总结了注浆法施工流程及质量控制措施,旨在为类似工程设计及施工提供参考。Taking the section of a bridge head that needs secondary excavation and backfilling in an expressway project in Zhejiang Province as an example,this paper expounds the basic principle of grouting method,and reasonably selection of the grouting hole spacing,pressure,grouting amount and specific settlement observation parameters,which provides an effective reference for construction,obtains good grouting effect,and effectively controls the uneven settlement of subgrade.It summarizes the construction process and quality control measures of grouting method,aiming to provide reference for similar engineering design and construction.
