摘　　要：在地表面下开挖不同尺寸的圆柱形坑槽,用φ200mm的PVC做密封桶,分别对高贝利特水泥混凝土和普通硅酸盐水泥混凝土成型不同尺寸试件,进行自生体积变形试验。结果表明,混凝土自生体积变形存在明显的尺寸效应。试件尺寸大,混凝土自生体积变形减少。与普通硅酸盐水泥混凝土比较,高贝利特水泥混凝土自生体积变形减小的幅度较小。High Belite cement concrete and general Portland cement concrete molded in excavated cylindrical pits with different size under the ground and in sealed PVC buckets with φ200mm are tested on autogenous volume deforma- tion. The results show that size effect of autogenous volume deformation of concrete is obvious, and the autogenous volume deformation of concrete reduces with specimen size increasing. Compared with general Portland cement, the reduction of autogenous volume deformation of high Belite cement concrete is lower. At last, size effect of autogenous volume deforma- tion of high Belite cement concrete is analyzed.
