The Analysis of Ground Behavior on the Crossing Construction Under Railroad Using Field Measurement

We analysed the affection to subgrade that railway underground crossing construction make with studying displacement of subgrade of each construction methods and processing of Front jacking method and Pipe roof method with already-measured data(during the construction) and additionally-measured field test data in railway underground crossing construction. We measured vertical and horizontal displacement at two construction places of front jacking method and pipe roof method each, and we analysed the results of the measurement at each stage of construction to applied to the excution of construction.
