AI Article Synopsis
- The article discusses field records from the EPB shield machine used in the construction of Metro Line No. 5 in Tianjin, China, focusing on its performance metrics.
- Key parameters analyzed include cutterhead rotation speed, torque, shield thrust, and advance rate, which are crucial for understanding the tunneling process.
- The dataset also considers the impact of soil types, such as silt and clay, on energy consumption and overall construction efficiency in the tunneling process, as explored in a related study.
Article Abstract
The data presented in this article 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 figures. 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 R 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. These field data are applied to evaluate the construction efficiency in the article titled "Construction efficiency of shield tunnelling through soft deposit in Tianjin" [1].
