Back Analysis of Infiltration Flow Parameters and Its Application in Engineering

Zhou Min Dai Yongxin (Maanshan Institute of Mining Research) Zhu Qingshan (Nanshan Mining Co.Ltd,Maanshan Steel)  
Advantages and disadvantages of neural network method were analysed.By the maxmium error learning algorithm,inversion solution was made on the infiltration parameters of rock body which decide the flow pattern.Based on the observation data of water head of the slope infiltration flow field and the data of on site water injection test,back analysis of infiltration parameters is made using neural network method.Taking a large open pit slope as the case,this method was used to determine the infiltration coefficient of the rock body of slope.Finit element calculation was made and correspondent computing program compiled.The engineering application has shown that the predicted value of water head coincides with that of observation,providing a basis for the analysis of slope stability.
