| Abstract: | The parameters of Dtmcan Model in rock-fall material is of great influence on the calculation results of concrete faced rock-fill dam, so it is very significant to determine the parameters by a simple method. The statistical principle of Dtmcan model of the rock-fill material is analyzed based on 13 rock fill dam engineerings and the relations beteween the parameters and their dry density of limestone and sandy gravel are built, which is of significance to Duncan Model parameter calculation. |
