摘　　要：文中以某建筑工程为例,研究深厚淤泥层基坑开挖岩土动态监测及其应急处理,从基坑监测数据信息、地层的因素、基坑周边环境影响三方面对动态监测展开分析,并提出以旋喷锚索为核心的加固应急处理方案,总结其成孔、注浆、张拉控制等关键技术。监测结果表明,该处理方案的加固效果较好,可为类似工程提供参考。Taking a construction project as an example,this paper focuses on the dynamic monitoring and emergency treatment of excavation excavation in deep silt layer,analyzes the dynamic monitoring mainly from three aspects:foundation pit monitoring data information,formation factors and the impact of the surrounding environment of the foundation pit,proposes the reinforcement emergency treatment plan with the rotary jet anchor cable as the core,and summarizes the technical requirements of holes formation,grouting,tension control and other links.It is found that this treatment scheme has good reinforcement effect and can provide reference for similar projects.
