摘　　要：在拱梁分载法坝体应力分析时 ,需要合理确定坝基岩体的变形模量值。为此 ,在溪洛渡水电站双曲拱坝的坝基变形模量计算中采用平面有限元法计算地基的“综合变形模量”。Deformation modulus for dam foundation rock must be determined reasonably when stress in dam is analyzed with arch and cantilever trial load method .Therefore,in computation of foundation deformation modulus for double curvature arch dam at Xiluodu project,“overall deformation modulus” in foundation is estimated with two dimensioned finite element method,so influence of topography and geology on deformation of arch dam foundation is reflected.
