Analysis of Influence of Cementitious Gravel Material on Inlaid Concrete Face Dam
Combined with the structural layout of Yangqu inlaid concrete face rockfill dam and the actual situation on site,triaxial tests of cementitious sand and gravel(CSG)materials were carried out,with cement dosage controlled at 10 kg/m3,20 kg/m3,30 kg/m3 and 40 kg/m3 respectively,to analyze the influence of cement dosage on the elastic modulus of cementitious sand and gravel materials;through two-dimensional and three-dimensional finite element calculations,the influence of high modulus cementitious sand and gravel filling in different areas on the stress and strain of the dam body and face plate was analyzed,providing a reference for the subsequent on-site construction of cementitious sand and gravel materials.
