In the station improvement work etc., when carrying out excavation under a business line, the construction girder for railways may be used as a temporary temporary reception of a rail. At the time of construction of the construction girder, it is necessary to dig the ballast of the target part in advance. It is common practice to use heavy equipment for ballast drilling, but in business line proximity work, the operation time is limited per day, so if the amount of ballast removal is large, the overall process may be greatly affected.This time, we report because we performed nonlinear finite element analysis to finally determine fracture
