Tunnel uneven settlement-based train derailment accident scenario construction method

Abstract

The invention discloses a tunnel uneven settlement-based train derailment accident scenario construction method. The method comprises the following steps of: S1) establishing a basic model of subway tunnel uneven settlement according to variables causing tunnel foundation uneven settlement; S2) acquiring an uneven settlement volume and inclined deformation data of a tunnel foundation, and carrying out concentrated analysis on the acquired data information by combining current conditions of a subway tunnel, so as to obtain a rail deformation or settlement volume; S3) amplifying the rail deformation or settlement volume, and acting the amplified rail deformation or settlement volume on a high-speed subway train to obtain a train instability and derailment model; and S4) virtualizing above accident scenario and carrying out animation display. According to the method, an emergency preparation strategy is provided for the safe operation services after the opening of subways in cities, so that the train derailment accidents caused by the tunnel uneven settlement can be previously displayed and then convenience is brought to intensify the rescue preparation.

Description

technical field [0001] The invention relates to the field of urban subway operation emergency management, in particular to a method for constructing train derailment accident scenarios based on uneven settlement of tunnels. Background technique [0002] With the rapid development of society, the urban population is dense, the space is crowded, and the traffic is blocked. The development and utilization of urban underground space is the only way for urban development in the 21st century. Many scholars in the world call the 21st century "the century of underground space development and utilization." ". [0003] The subway is the lifeline project of urban construction. While the construction of the subway provides convenience for the transportation of the whole city, it also buryes a huge hidden danger for the safety of the city. The uneven settlement of the subway tunnel seriously affects the operation safety of the train and ensures the safety of the subway tunnel. Safe oper...
