盾构隧道精细有限元模拟数据集

数值模拟的隧道外荷载主要包括竖向土压力、侧向土压力、地基反力、隧道结构自重，侧压力系数取地基抗力系数（深圳地铁隧道主要位于粘性土地层）。由有限元软件Abaqus依次仿真分析：管片弹性模量-收敛变形关系、收敛变形-纵缝张开关系和螺栓预紧力作用。数据量约61.3MB。

The external loads considered in the numerical simulation of tunnels mainly include vertical earth pressure, lateral earth pressure, foundation reaction force, and the self-weight of tunnel structures. The lateral pressure coefficient is taken as the foundation resistance coefficient, as Shenzhen Metro tunnels are mainly located in clayey strata. Sequential simulation analyses are carried out using the finite element software Abaqus, covering the relationship between segment elastic modulus and convergence deformation, the relationship between convergence deformation and longitudinal joint opening, and the effect of bolt pretightening force. The total dataset size is approximately 61.3 MB.
