摘要

Based on the Richards differential equation of saturated and unsaturated seepage, taking Houguan Lake lakeshore zone in Wuhan as the study area, and taking two-dimensional phreatic seepage trough in groundwater dynamics as the indoor physical model, the existing device was designed and improved, and an experimental method was proposed for the study of rainfall infiltration of the existing riparian slope. The device improves the slope simulation of uneven rainfall problem, overcomes the slope can not change the shape of the problem, can help complete a variety of physical quantity monitoring. The experimental personnel used the modified device to analyze the slope rainfall infiltration and seepage law under different rainfall intensity (long and weak, short and strong), the slope rainfall infiltration and seepage law under different rainfall intensity (long and weak, short and strong).
