摘　　要：分析了一些国内外相关资料,对目前国内外研究人员通过试验得出的高性能混凝土弹性模量计算公式和柏松比的试验结果进行了对比与总结,得到可以用高强混凝土弹性模量计算公式计算普通集料高强混凝土弹性模量,以及高流动混凝土的弹性模量比普通混凝土的弹性模量低、高性能混凝土的泊松比与普通混凝土的泊松比相差不多等一些有价值的结论.The paper compares and analyzes some formulae for calculating the modulus of elasticity and Poisson ratio of HPC, which are derived from experiments. Some useful comments and suggestion are gaven, for instance, the modulus of elasticity of high strength concrete(HSC) with common aggregate can be calculated by the formula for the modulus of elasticity of HSC, the modulus of elasticity of self_compacting HSC is lower than that of common concrete, and the possion ratio of high performance concrete is closed to common concrete's possion ratio.
