Authors have conducted the development of new in-situ piling technique for the constructive utilization of space above the railway or railway facilities (ex. station). In the proposed technique, piling machine will be established on the prefab decks constructed above the railway platform. And spread foundation made of steel plate will be also employed as the footings of the deck. In the development activities, studies on vertical and horizontal bearing capacity of spread footings made of steel plate are carried out. To examine the vertical bearing capacity of steel plate, model loading tests and 3-dimentional non-linear finite element analyses were conducted. From these studies, it was found that vertical bearing capacity of steel plate could be estimated by ordinal design code and that closeness between two footings expected in the new piling method had almost no effect on bearing capacity. In the examinations on horizontal bearing capacity of steel plate, development of method to improve the horizontal resistance of spread footing was canied out. For this purpose, model loading tests were conducted and effectiveness of the method was confirmed.
