煤矿斜井隧道管片力学性能及防水性能仿真分析

Simulation Analysis on Mechanical Property and Waterproof Performance of Segment in the Shield Construction Tunnel

摘要: 在盾构法施工煤矿斜井隧道的过程中，管片作为衬砌体系的受力主体，需要承受隧道周围的水、土压力和其他各种荷载，对其力学性能和防水性能有较高的要求。本文采用数值模拟方法，进行了盾构拆解区域管片力学性能和防水性能的仿真分析。通过分析，我们得到了管片的内力、变形、接缝张开量和错位量等参数，为工程的顺利实施提供了理论支撑。

Abstract: As the main body of coal mine slant in the shield construction, segment need to bear the sur-rounding water pressure, soil pressure and various other loads. It has high requirements for me-chanical property and waterproof performance of segment. In this paper, the simulation analysis was studied on mechanical property and waterproof performance of segment in the shield con-struction tunnel. Through analysis, internal force, deformation, seam opening and dislocation of the segment are obtained. It provides theoretical support for the implementation of the project.
