Plastic concrete,as a kind of low cost and excellent impermeable material,has the characteristics of large strain,low elastic modulus,and low strength,which can adapt to large deformation.Based on the practical application of plastic concrete in Doupo Reservoir reinforcing project,the advantages and disadvantages of two construction methods are analyzed.One is to conduct curtain grouting first,and then construction of plastic concrete diaphragm wall;the other is construction of plastic concrete diaphragm wall first and then the curtain grouting,that could provide reference for similar project construction.
