上海轨道交通8号线三期暨集运系统工程为上海轨道交通首次引入的胶轮路轨系统。详细介绍了该工程胶轮路轨系统与钢轮钢轨系统下部结构荷载的差异,通过墩柱有无纵向线刚度要求对墩柱设计尺寸的影响、新规范对墩柱抗震计算的影响及墩柱主筋超配产生问题等的讨论,提出集运系统下部结构设计的思考。 The third phase of Shanghai Metro Line 8 cum transportation system project is the first rubber tire rail system introduced in Shanghai Metro. This paper introduces in detail the differences of the load between the engineering rubber rail system and the steel rail system substructure, the influence on the design dimension of the pier through the presence or absence of the longitudinal stiffness of the pier, the influence of the new code on the seismic calculation of the pier and the main reinforcement Over-allocated problems such as the discussion put forward the design of the transport system under the structure of thinking.
