QPZ型盆式橡胶支座是一种具有独特优点的新型支座。本文通过对三个2000kN的单向活动支座的力学性能试验,测定了盆环的受力状态、竖向压缩变形和盆环径向变形、摩擦系数和水平力对盆环应力的影响,这种支座可以很好地满足桥梁的使用要求,证明了设计理论的正确性。它在公路、铁路和城市桥梁结构中都有广泛的应用前景。
QPZ basin rubber bearing is a new type of bearing with unique advantages. In this paper, through the mechanical tests on three 2000 kN unidirectional movable supports, the influence of the stress state, the vertical compression deformation and the radial deformation of the bowl ring, the friction coefficient and the horizontal force on the stress of the bowl ring are measured Supports can be very good to meet the requirements of the bridge to prove the correctness of the design theory. It has a wide range of applications in the highway, railway and urban bridge structures.
