Review of Dams and Dikes with Composite Geomembrane Impervious Structure

In this paper,several representative domestic and abroad dams and dikes with composite geomembrane impervious sheet were illustrated.In which,8dams were built recently,5were faulted dams repaired with composite geomembranes,2were cofferdams on the large river.These projects had been finished between1972to1999.The structural sections and characteristics of these dams and dikes are described in this paper.Some designing and constructional defeats of these dams and dikes are criticized in order to raise the technique level of composite geomembrane dams and dikes.
