STUDY ON DIVERSION LENGTH OF THE INCLINED CAPILLARY BARRIER USING CRUSHED SCALLOP SHELL PARTICLES

Abstract

 The authors found that an employment of crushed scallop shells in the lower layer instead of gravel greatly helps to reduce the transport of the finer particles in the upper layer into the lower layer, and to provide an effective function of capillary barriers. In this study, the diversion lengths are measured in the field experiments using crushed shells instead of gravel in the lower layer, and compared it with the diversion lengths of the inclined capillary barrier having cover soil. As the result, the authors make clearly the diversion length of the inclined capillary barrier having cover soil.
