摘要 地铁盾构区间在下穿深埋污水管线时,由于土层损失,会造成一定程度的管道下沉和变形,影响管道运行安全,进而影响地铁区间隧道的实施及运营安全。通过计算分析,量化盾构对管道的影响,从而确定地铁施工需要采取的控制指标及污水管道必需的迁改范围。对于大管径污水管道,在地铁前期设计时必须作为风险源进行严格计算和专项设计,以尽量减小地铁与污水管道间的相互影响。 During the underground deep burying of sewage pipeline in metro shield interval,a certain degree of pipeline subsidence and deformation will be caused because of soil loss,which will affect the safety of pipeline operation,and then affect the implementation and operation safety of metro tunnel.By calculation and analysis,the influence of shield on pipeline is quantized so as to determine the control indicators to be adopted for the metro construction and the relocation range necessary for sewage pipeline.For the large-diameter sewage pipelines,the strict calculation and special design as a risk source must be carried out in the preliminary design of metro in order to minimize the interaction between metro and pipeline.
