摘要
结合变位控制原理,对盾构法下穿既有线引起的地表沉降进行分析预测,按照施工步序,把地表沉降分为5个部分,并针对每个部分提出具体的控制措施,很好的控制了地表沉降,保证了既有线的安全运营,对同类工程具有一定的指导意义。
Combining with displacement control principle, it analyzes and predicts the ground surface subsidence caused by under-crossing existing railway line with shield method. According to construction steps, it divides ground surface subsidence into 5 parts, and puts forward specific control measures for every part, effectively controls ground surface subsidence, and guarantees the safe operation of existing railway line, which has certain guiding significance for similar engineering.
