摘　　要：基坑监测数据是反映基坑施工安全的重要指标依据,当监测数据超过预警值时,需对基坑支护体系采取加强措施。本文以华欣财富广场项目为例,为保证基坑开挖及施工安全,对地下室开挖过程中原支护体系突发位移的问题进行应急处理,采取坑底反压土结合φ609×16mm钢管斜抛撑的方式对基坑进行应急加固,分析了地基反压土+斜抛撑的支撑加固方式在应对基坑位移时的应用效果。结果证明,采用该技术对基坑支护进行加固,保证了项目的施工安全。Foundation pit monitoring data is an important indicator for reflecting the safety of foundation pit construction.When the monitoring data exceeds the warning value,strengthening measures need to be taken for the foundation pit support system.This article takes the Huaxin Fortune Plaza project as an example to ensure the safety of pit excavation and construction.Emergency response to sudden displacement of the original support system during basement excavation.The pit bottom back pressure soil combined withφ609×16mm steel pipe diagonal bracing was used for emergency reinforcement of the pit.It analyzes the application effect of the support and reinforcement method of foundation back pressure soil+diagonal bracing in dealing with foundation pit displacement.The results show that using this technology to reinforce the foundation pit support ensures the construction safety of the project.
