Data on performance and variation index for shield tunnelling through soft deposit

The data pertain to field records of EPB shield machine in Metro Line No.5 in Tianjin, China. Field performance of shield machine (cutterhead, screw machine, and shield advancing) are shown in the file. Specifically, the database consists of the main parameters for shield tunnelling including cutterhead rotation speed, cutterhead torque, screw machine rotation speed, screw machine torque, shield thrust, and shield advance rate. In addition, the calculation process of energy consumption and variation index during the tunnelling are displayed. The value of the dataset is the consideration of silt or clay soil encountered in the shield tunnelling area including the proportion of soils, grain gradation, and effects on performance and energy consumption of different parts in shield machine.

本数据集涉及天津地铁五号线EPB盾构机的现场记录。文件中展示了盾构机（切割头、螺旋钻机及盾构推进）的现场性能。具体而言，数据库包含了盾构隧道施工的主要参数，包括切割头转速、切割头扭矩、螺旋钻机转速、螺旋钻机扭矩、盾构推力及盾构推进速率。此外，还展示了隧道施工过程中的能耗及变化指数的计算过程。数据集的价值在于对盾构隧道施工区域遇到的淤泥或粘土土壤的考量，包括土壤比例、颗粒级配以及对盾构机各部件性能和能耗的影响。
