摘　　要：介绍了预制装配式钢制波纹管地下综合管廊在非液化和可液化场地土环境下的系列振动台缩尺模型试验。研究结果表明:场地土与结构响应存在明显的相互影响,设计计算时应视为土-钢组合结构;管廊及其周围的土体在两类场地的动力响应存在明显的区别。具体而言,管廊及土体在可液化场地的加速度响应远小于其在非液化场地的加速度响应;在非液化场地中,管廊及内部支架结构在大震作用下均处于弹性状态,而在可液化场地中,管廊及内部支架在大震作用下均发生了一定程度的塑性破坏。为这类管廊的抗震设计计算和工程应用提供了试验和理论依据。In the study,a set of shaking table tests are conducted to investigate the seismic behavior of prefabricated corrugated steel utility tunnels on non-liquefiable and liquefiable ground,respectively.The results indicate that there is an obvious interaction between the tunnel and surrounding ground,and the tunnel and ground should be considered as a soil-steel composite structure.The dynamic responses of the tunnel and its surrounding soil in the two sites are obviously different.Specifically,the acceleration responses of the tunnel and soil on liquefiable ground are much less than those on non-liquefiable ground.Under rare earthquakes both the tunnel and brackets remain elastic on non-liquefiable ground.However,the tunnel and brackets occur certain plastic failure on liquefiable ground.This research provides a reference for the design and construction of prefabricated corrugated steel utility tunnels.
