    摘要:

    胶凝砂砾石坝筑坝材料具有较大的变异性，有必要研究其参数概率分布形式。通过对3座大坝工程现场试验资料的分析，基于χ2或K-S有限比较法对胶凝砂砾石材料参数进行概率统计分析，提出参数分布的推荐概型：采用正态分布作为密度的分布概型；采用对数正态分布作为弹性模量的分布概型；采用对数正态分布作为强度的分布概型；采用β分布作为泊松比ν的分布概型。对胶凝砂砾石坝相关距离问题进行探讨，指出其竖直向相关距离可取0.5~2.0 m，水平向可取5~30 m。

    Abstract:

    The heterogeneity of hardfill is obvious, so it is of necessity to study its parameter’s statistical distribution. Take three hardfill projects with field tests’ data as research objects, the probability and statistical analysis have been done based on χ2 or K-S finite contrast method, and the recommended probability distribution models have been put forward：recommend normal distribution to fit the probability of density; recommend lognormal distribution to fit the probability of modulus of elasticity; recommend lognormal distribution to fit the probability of strength parameters; recommend β distribution to fit the probability of poisson ratio. Moreover, the correlation distance of hardfill dam is also discussed. Results are that the vertical correlation distance and the horizontal correlation distance are 0.5~2.0 m and 5~30 m, respectively.
