盾构下穿引起的既有线路轨道变形与列车运营作用研究
Research on Existed Track Deformation Induced by Down-traversing Shield Tunnel and Interactive Influence on High-speed Train
摘要
Abstract
The down-traversing shield tunnel excavation is likely to disturb the existed railway foundation and result certain deformation of ground layer, settlement of subgrade and track irregularity, which may impact surrounding environment, affect normal operation and endanger the passengers, and what is more, damage the railway. In this paper, a track-subgrade-down-traversing shield tunnel model is established with finite element software ABAQUS to analyze the influence of down-traversing shield tunnel. The interactional relation between the deformation of track, the track layer joints and the operation of high-speed train caused by underpass tunneling is analyzed in view of the interaction between high speed railway structures based on vehicle track coupling dynamics theory.关键词
