Technical problems in rising concrete gravity dam: a case study of the “Tan Giang” dam in Ninh Thuan province

Abstract

     Rising the gravity dams including concrete dams in order to enhance reservoirs' capacity is the concern of the water consumers. Beside technical and engineering measures for taking dam higher many problems posed to the rising part in particular and the whole concrete dam in general are required detail calculations to ensure the safety of the new dam. In this article technical solutions for raising the concrete gravity dam are proposed and hence calculate dam's stability and durability applied to Tan Giang concrete gravity dam in Ninh Thuan province. Remarks on raising concrete gravity dams are also included providing maximum efficiency of the project.
