摘要:

为探究波纹钢板综合管廊在低周循环往复荷载作用下的滞回性能,以某波纹钢板综合管廊实际工程为依托,采用数值模拟与试验相结合的方法,研究管廊在横向、纵向、竖向共6种荷载工况下的抗震性能,以及法兰连接、法兰厚度、管廊壁厚(波纹钢板厚度)、螺栓位置等参数对结构滞回性能的影响。研究结果表明: 1)在低周循环往复荷载作用下,波纹钢板综合管廊塑性变形能力强,抗震性能良好;但管片拼装节点处是其薄弱位置,易发生脱开现象。 2)法兰对结构力学性能及滞回性能的影响显著,但法兰厚度改变对其影响较小。 3)环向法兰上螺栓的位置对结构纵向滞回性能影响较大,对其他方向滞回性能则几乎无影响。 4)波纹钢板厚度是影响结构抗震性能的关键因素。

Abstract:

In this study, the hysteresis performance of corrugated steelplate utility tunnel under lowcycle cyclic load is investigated by conducting a case study on a corrugated steelplate utility tunnel. In addition, numerical simulations and tests are employed to examine the seismic performance of the tunnel under six load conditions, including transverse, longitudinal, and vertical loads and the influence of flange connection and thickness, utility tunnel thickness, and bolt position on the hysteresis performance of the structure is characterized. The present findings are stated as follows: (1) The corrugated steelplate utility tunnel exhibits strong plastic deformation ability and appropriate seismic performance under lowcycle cyclic load. However, the segment assembly joint is a weak position that can be easily detached. (2) Although the mechanical and hysteresis properties of the structure are remarkably influenced by the flange, the variations in flange thickness have a marginal effect. (3) The position of the bolts on the circumferential flange considerably influences the longitudinal hysteresis characteristics of the structure but marginally impacts the hysteresis characteristics in other directions. (4) The thickness of the corrugated plate is a key factor affecting the seismic performance of structures.
