列车荷载作用下紧邻垂直多孔隧道环境振动分析
Ambient vibration analysis of adjacent perpendicular multi-tunnels under train loads
摘要
Abstract
At present, the commonly used ambient vibration evaluation criteria caused by train vibrating loads is based on the test data and calculation results of a single train, which can not reflect the real vibration situations with multi-tunnels because of the rapid development of rail transit in China.There are four tunnels crossing each other between Hongshan Square Station and Zhongnan Road Station.which are the second line and the founh line of Wuhan rail transit.The complicated multi-tunnels were simplified as four adjacent perpendicular tunnels with different distances according to its practical characters.Three-dimensional calculation models are established; and ambient vibration and spectrum characteristics are analyzed with different train numbers.different tunnel depths and different tunnel net distances.Approximate empirical formulas are suggested based on the calculation results and the vibration influence areas are determined accordingly.The research resuILs can provide references to forecast and evaluate the ambient vibration for similar projects in future in China.关键词
