摘　　要：土石坝渗流量是土石坝渗流监测的重要参考,直接反应土石坝渗流安全稳定状态。以某水库土石坝主坝渗流量监测分析为例,采用MATLAB分析软件,考虑15个影响因子,建立渗流量监测数据统计模型,得到各因素的影响系数,基于经验分析构建各影响分量占比公式,计算水压、降雨量和时间的影响分量占比分别为67.25%、26.59%和6.16%,得到土石坝防渗体处于安全稳定状态的结论。The seepage flow volume is an important indicator of seepage flow monitoring of earth-rock dams,which can directly reflect the safety and stability of the dams.This paper takes the seepage flow monitoring analysis of the main dam of a reservoir as an example,using the MATLAB analysis software and considering 14 influencing factors,to establish a statistical model for seepage flow monitoring data.The influence coefficients of each factor are obtained,and a formula for the proportion of each influencing factor based on experience analysis is constructed.The proportions of influence factors are calculated to be 67.25% for water pressure,26.59% for rainfall,and 6.16% for time,leading to the conclusion that the seepage flow monitoring data of the earth and rock dam is reliable.
