摘要
依托土压平衡式盾构机在富水砂层中的施工实例,结合盾构机的工作原理和结构特点,总结盾构机在富水砂层中施工时的沉降规律,分析各阶段地面沉降的原因,有针对性的采取沉降控制措施,利用信息化施工手段,有效控制地面沉降。
In this paper, based on construction case of EPB Shield Machine in the water-rich sand layer, combining with the working principle and structure characteristics of the shield machine, the settlement taws during the construction of EPB Shield Machine in water-rich sand layer is summarized. According to the cause analysis of ground settlement in different stages, the targeted settlement control measures are suggested, Measures of informationization construction are used to effectively control the ground settlement.
