嵌入式轨道PVC管埋设方式对轨道结构受力影响分析
Analysis on Force Effect of Embedded Track PVC Tube on Track Structure
摘要
Abstract
In order to meet the demand of urban rail transit operation, embedded track structure has been widely used. The rail for this track structure is laid in the groove with elastomer, and PVC tube may be used in the elastomer to cut cost and save material. The comparative analysis of displacement of rail, mechanical characteristics of track side polymers and mechanical characteristics of track slab under different settings is conducted with finite element model. The results show that the choice of different embedding ways has a little effect on trackside polymer composite stress, but great one on the maximal tension stress of track slab. In view of the bond failure between polymer composite and other materials caused by site construction and aging behaviors of polymer composite material, the track structure should adopt embedded PVC tube outside the rail, and 3 to 6 MPa of elastic modulus of the composite is recommended.关键词
