摘　　要：为了确定排沙量与时间、排沙量与水流量的函数关系,采用SAS软件做线性回归得到排沙量与时间的函数关系式,再利用所求函数在区间[0,24]上进行积分得到总排沙量为1.93962亿吨.对于排沙量与水流量之间的关系,按时间分为两段进行拟合,最终确定了排沙量与水流量的函数关系.In order to-find out the function relationship between sand discharge capacity and time, and the relation between sand discharge capacity and tonnage, SAS program is applied to make linear regression and find the function equation of the former relationship, Then by integrating the function acquired on the intervals [0, 24], the total sand discharge capacity is obtained, by fitting in the two phases of time, the function gained in the end. that is 193.962 million tons. As for the latter relationship, expressions of the sand discharge capacity and tonnage is
