摘要

装配式车站可有效提高地铁工程建设质量和效率,是城市轨道交通高质量发展的趋势。本文以深圳地铁首个采用新型C-H-C接头的全新装配式车站为背景,进行了装配式地铁车站静力模型试验,在此基础上使用有限元软件ABAQUS建立装配式地铁车站整体框架有限元模型。通过弹簧-实体接触模拟C-H-C接头的非线性特性,采用非线性弹簧模拟土-结构相互作用,建立地层-结构非线性相互作用有限元分析模型,对不同设计荷载工况下的结构静力反应进行数值模拟。结果表明:通过与模型试验结果进行对比分析,验证了数值模型的合理性;相较于低水位工况,高水位工况结构底板的内力、变形显著增大,底板设计时应按照压弯构件考虑;内力主要通过顶、底角点构件接头传递,且主要受接触面积影响。本文成果验证了基于新型C-H-C接头的装配式地铁车站受力合理可行。

Abstract

Prefabricated station can effectively improve the quality and efficiency of engineering construction, which is the inevitable trend of high-quality development of urban rail transit. In this paper, a static model test of an assembled metro station is conducted in the context of the first new assembled station of Shenzhen metro with a new C-H-C joint. The finite element model of prefabricated subway station frame is established according to the static model test of prefabricated subway station joint. The nonlinear characteristics of C-H-C joint were described by spring-solid contact, and the nonlinear spring was used to simulate soil-structure interaction, and the finite element analysis model of stratiform-structure nonlinear interaction was established. The static response of the structure under different test conditions was numerically simulated. Test results indicate that the mechanical responses of the physical model and the numerical model were consistent, then, the rationality of numerical model was verified. Compared with the low water level condition, the internal forces and deformation of the bottom slab were significantly amplified in the high-water level condition, and the bottom plate should be designed as beam-columns. The internal forces are mainly transmitted through the joints at the top and bottom corner, and the amplitudes are mainly affected by the contact area.
