关于佛山地区软土地质深基坑监测技术探析

Analysis on the Monitoring Technology of Deep Foundation Pit of Soft Soil in Foshan Area

软土地区深基坑一直是个难题,如何在设计过程中保证基坑稳定性,保证周边变形安全,又能适当的降低成本,是个一直避不开的难题。本文以佛山地区某软土深基坑项目作为研究对象,在施工过程中,通过对基坑支护结构监测及周边环境监测,得到有效数据指导施工及设计,保证了基坑安全。同时通过分析软土地质情况、现场表征变形、周期监测数据、基坑支护结构设计等因素,在设计、施工、及监测过程中提出积极有效的建议及技术支持。本文以对该项目的实际情况进行综合分析,总结了宝贵的经验和教训,为今后类似工程项目提供了有益的参考和借鉴。

Deep foundation pit in soft soil area has always been a difficult problem.How to ensure the stability of the foundation pit in the design process,ensure the safety of the surrounding deformation,and reduce the cost appropriately is a difficult problem that cannot be avoided.This paper takes a deep foundation pit project in soft soil in Foshan as the research object.During the construction process,through monitoring the foundation pit support structure and the surrounding environment,effective data is obtained to guide the construction and design,ensuring the safety of the foundation pit.At the same time,through analyzing the soft soil conditions,on-site characterization deformation,periodic monitoring data,foundation pit support structure design and other factors,active and effective suggestions and technical support are put forward in the design,construction and monitoring process.This paper comprehensively analyzes the actual situation of the project,summarizes valuable experience and lessons,and provides useful reference for similar projects in the future.
