Abstract

Abstract: Abstract:By using the finite element software ANSYS, the tunnel anchorage of Puli Bridge was analyzed. The stability of tunnel anchorage under non-dynamic tensile load in the main cable was calculated. When earthquake occurs, with the consideration of anchor piug body to tensile load in main cable, the four corners of the bottom surface and the two vertexes of front and back surface were monitored. Through the stress and stress amplitude analysis of monitored points, it shows that the response of the plug body of former anchor surface is more strongly than that of the back surface.

Key words: bridge engineering, tunnel anchorage, dynamic tension force, time curve

摘要： 运用ANSYS有限元软件，以普立特大桥隧道式锚碇为原型进行三维仿真分析。仿真计算了隧道式锚碇在主缆非动力设计张拉荷载下的稳定性;地震时，从锚塞体对主缆动张拉力荷载的响应方面考虑，以锚塞体底面4个角点及锚塞体前后锚面2个顶点为监测点，分析了计算所得的应力及应力幅值。结果表明:锚塞体前锚面质点的响应比锚塞体后锚面质点响应更加强烈。
