摘要
在盾构穿越复合地层沉降敏感区段时,对该区段的施工沉降进行了严密观测,并对监测数据进行了全面分析,总结出上软下硬复合地层的沉降变形的一般规律。在工程实施中采取有针对性的沉降控制措施,确保敏感区段的沉降控制在允许范围之内。
When tunnel shield was passing through the settlement-sensitive section in complex soil strata, the corresponding settlement of the section was carefully measured. The monitoring data were comprehensively analyzed, then general rules of settlement and deformation in soft upper layer and rigid lower layer complex soil strata was summarized. Some settlement control measures were taken in the advancing process to secure the settlement was within the allowable range.
