Abstract
Steel pipe sheet piles with impervious joints usually are used for impervious sea walls of coastal waste disposal sites. We have proposed to fill between steel pipe sheet piles and U-type sheet piles with soil impervious materials as the impervious structure, then investigated impervious performance for over a year in waters. In this study, the materials samples were taken from the impervious structure, and impervious performance test, vane shear test, water content test were carried out to investigate properties of the materials. In addition, the effect which the materials may leak from holes in sheet piles was examined.
