摘要

采用有限元计算分析软件ADINA

建立加高方案渗流分析模型

对渗流场进行数值分析。通过反演分析得到的材料渗透系数远大于室内试验值

加高后浸润线普遍升高。由实测水头值反演获得的渗透系数综合考虑了工程现场条件

此渗透系数作为加高方案的材料渗透系数是合理的。加高后尾矿坝浸润线升高

必须加强防渗排水措施

最好在加高后加设浸润线观测措施。

Abstract

A model of seepage analysis for heightening planning of a tailings filling dam is constructed by using ADINA

in which seepage field of the tailings filling dam is analyzed.The coefficient of material permeability of the tailings filling dam obtained from inverse analysis is greater than that from laboratory experiment.Seepage free surface from the model is higher than practically measured seepage free surface.The coefficient of material permeability obtained from inverse analysis is more reasonable because the environmental conditions of the tailings filling dam are taken into consideration.After the tailings filling dam is heightened

seepage free surface will become higher

so seepage-proofing equipment and drainage equipment should be added.If possible

surveying equipment for seepage free surface should be added as well.
