摘要
软黏土地层分布广泛,因软黏土强度低、高触变性、高压缩性、低渗透性与结构性不良等性质,深基坑工程针对自身及周边环境变形安全管控,必须制定有效的监控制实施方案,对施工过程各阶段变形进行监控,监测数据科学指导施工,及时控制施工进度及施工工法的运用,确保施工全过程安全。结合软黏土地区基坑工程监测及施工组织实践,分析软黏土基坑工程变形规律。
Soft clay layers are widely distributed.Due to the low strength,high thixotropy,high compressibility,low permeability,and poor structural properties of soft clay,deep foundation pit engineering must develop effective monitoring system implementation plans for its own and surrounding environmental deformation safety control,monitor deformation at each stage of the construction process,scientifically guide construction with monitoring data,timely control construction progress and the application of construction methods,to ensure safe construction throughout the entire construction process.Based on the monitoring and construction organization practice of foundation pit engineering in soft clay areas,this article analyzes the deformation law of soft clay foundation pit engineering.
