A Study on the Load Over a Cut and Cover Tunnel Caused by Train

Satoshi TAKISAWA, Shiro TANAMURA


  In this paper, the authors describe how to calculate the characteristic values of the stress caused by the vertical earth pressure, which will be used in checking the section of box culvert (general structural type of cut and cover tunnel) crossing underneath tracks. This study features consideration of load distribution of rails, and revision of the existing calculation method from some aspects. Although the calculation method indicated here is considered to be appropriate for general ballasted tracks, other methods should be adopted in case the calculation results show that the presented method is inappropriate.
