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

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

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.
