Self Moving Type Temporary Support Bracket Support Mechanism and Deformation Monitoring

对拱形巷道自移式临时支护支架结构的特点及支护原理进行了分析,并利用ANSYS软件和光纤内的布里渊散射应力传感技术对巷道变形监测特点进行了力学仿真和监测仿真。仿真得到了自移式临时支护拱形顶部的受力分布情况,并验证了布里渊散射应力传感技术对于监控巷道自移式临时支护支架是有效的。

This paper analyzes the structure characteristics of the arch tunnel self moving type temporary support bracket and the supporting principle,and carries on the mechanical simulation and monitoring simulation on the characteristics of tunnel deformation monitoring using ANSYS and sense technology of the Brillouin scattering stress in the optical fiber.Then we obtain stress distribution of the self moving type temporary support bracket on the top of arch by simulation and thus verify that the sense technology of the Brillouin scattering stress is effective for monitoring the arch tunnel self moving type temporary support bracket.
