CASE STUDY OF SLOPING CORE ZONE CONSTRUCTED BY CEMENT-STABILIZED MUDDY SOIL FOR LEAKAGE CONTROL IN SMALL EARTH DAM

Abstract

Most of irrigation reservoir dams were mostly accumulated with a mud soil in reservoir that caused the pollution and the shortage of reserved water. This mud soil generally is high-water-content and very soft clayey soil. In order to make efficient use of such a problematic soil as embankment soil, we have developed a new type method to repair the damaged embankment by means of the stabilized mud soil with cement stabilizer.
This paper describes the case study of sloping core zone constructed by cement-stabilized muddy soil that applied this method to prevent the leakage of an old small earth dam. It also represents the test results investigated the strength and permeability characteristics of the sloping core zone.
