THE FIELD EXPERIMENTS OF THE LARGE-SIZED SAND BAGS

Abstract

  The conventional shore protection facilities have been constructed using stones or a concrete block to resist wave force. However there are the problems of shortage of suitable resources and poor productivities on gravel building stones. For this, the sand bags consisting of geo-textile to be noted for its aspects of filled with the local outbreak soil labor saving on construction, and flexible characteristics to the transformation.
  In this study, field experiments for constructing shore protection facilities using sand bags were carried out on Japanese coast, and three construction methods were tested.The merits - demerits and coastal condition that each method was applicable were discussed.
