摘要:
In China, a large number of passengers during peak period are a key problem issue that results in a peak load on the subway tunnel. The irregular vibration due to the overloading of train will cause critical damage to rail track and foundations. Due to the lack of field monitoring data, the effects of trainload-induced irregular vibration to the stability of concrete foundation and surrounding area remain a crucial scientific challenge. In current study, a cross-river tunnel in Wuhan subway 2nd line was selected as a case study. The numerical m...
