ESTIMATION OF SLOPE STABILITY BASED ON LIMITED EQUILIBRIUM METHOD BY USING GEOTEXTILES TO ENHANCE DIKES AND DAMS CONSTRUCTION ON THE WEAK SOIL FOUNDATION IN THE MEKONG DELTA

Abstract

There are many methods to enhance construction works in the weak soil foundation in Vietnam and foreign countries, however, using geotextiles to enhance slope stability has still not applied commonly in design and construction. Although it has multipurpose usage, geotextiled has been applied only in transport construction and river bank protection works. Recently many works have been invested by using local material to build as dikes or dams against flood or salt water in the Mekong delta. The paper has introduced an approach about estimation of slope stability based on limited equilibrium method having geotextiles in dikes or dams construction in the weak soil foundation in the Mekong delta. By using Slope/W software, safety coefficient for slip circle has been estimated with many alternatives of geotextiles lavers.
