STRENGTH AND PERMEABILITY CHARACTERISTICS OF SMALL DAM EMBANKMENT CONSTRUCTED BY CEMENT-STABILIZED MUDDY SOIL

Abstract

Most of irrigation reservoir dams in Japan were damaged by a secular change because they were constructed over one hundred years ago. Such dams were mostly accumulated with a mud soil. 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 an example of repairing work of the reservoir dam embankment that applied this method for the first time. It also represents the results investigated the strength and permeability characteristics of the embankment.
