Abstract

Based on the idea of wrapping a part of foundation like a soilbag, a new reinforcing method for bearing capacity is proposed. The validity of this method is illustrated by the results of the model footing tests and the model vertical embankment tests. Then, as an application example in the real engineering practice, a reinforcing method utilizing soilbags for the ballast foundation under the railway sleeper is stated and its validity is demonstrated by model tests. So far, the soilbag has been mainly used to prevent a flow of soils from water. In this study, however, the mechanical meaning of the soilbag is studied on the basis of the dilatancy characteristics of granular materials and it is found that the soilbag may be used as a load supporting body such as a footing or a pile.
