모래질 갯벌의 지반공학적 특성 및 인공갯벌의 안정성

Abstract

. The researches on the construction of artificial coastal wetlands have been progressed in order tocope with the situation that the area of Korean tidal flat has ben reduced due to several coastal developments.This study, as a part of the project on construction of the artificial tidal flats, deals with the comparison of thegeotechnical characteristics between natural tidal flat and artificial tidal flat, and is also focused on the stabilityanalysis of tidal flats. Various laboratory tests were performed using disturbed and undisturbed samples, whichwere obtained from a sandy tidal flat in Korea. The stability of the sandy soils acumulated on the tidal flat wasinvestigated by comparing the shear strength of soil evaluated from laboratory test with induced shear stress dueto both current and wave action.
