摘要: 针对目前地铁车站结构设计中,结构截面刚度变化对车站结构内力的影响规律还有待进一步讨论分析的现状,以某地铁车站为例,利用ANSYS 13.0建立车站结构空间有限元模型。通过调整结构梁板刚度比和梁柱刚度比来探讨地铁车站结构内力的分布规律。由此得出结论:随着梁板刚度比的增大,各层板横向最大弯矩均减少,侧墙横向最大正弯矩增大,各层板纵梁最大弯矩均增大,柱子最大轴力减少;随着梁柱刚度比的增大,各层板纵梁最大弯矩和最大剪力以及柱子最大轴力均出现先增大后或减少或不变的现象,但以增大为主。

Abstract: For purpose of current situation that in current subway station structural design, the structural sectional rigidity variation influences internal force of the station structure and such influence principle calls for further investigation. By taking one real subway station for example, finite element model was built to simulate the station space by use of ANSYS 13.0. By adjusting the structural beam-slab rigidity ratio and slab-column rigidity ratio, the structural internal force distribution law of subway station was explored. Following conclusions are drawn as follows: With the increase of beam-slab rigidity ratio, the transverse maximum bending moment of slabs at all levels decreas is while the transverse maximum positive bending moment of side walls increasis and the maximum bending moment of slab longitudinal beams at all levels all increasis and column maximum axial force decreasis. With the increase of beam-column rigidity, the maximum bending moment of slab longitudinal beams at all levels and maximum shear force and column maximum axial force all showed signs of first increase then decrease or remaining unchanged, but increase is dominating.

Key words: railway engineering, structural engineering;spatial analysis, internal force of structure, the stiffness ratio of beam-slab, the stiffness of beam-column, law of variation
