摘要
堆石材料邓肯模型计算参数的选用对面板堆石坝的计算分析成果影响很大,在实际应用过程中,需要有简单易行的推求方法,以合理地用计算参数.分析了堆石材料邓肯模型参数的统计规律,通过分析国内13个已建或在建工程堆石材料的实测计算参数,以干容重为参照,给出了灰岩和砂砾石材料参数的推求公式,对于合理选用邓肯模型计算参数有一定的借鉴意义.
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.
