降雨下透明土边坡渗流与失稳模型试验可视化
Visualization of model tests on seepage and instability of transparent soil slopes under rainfall conditions
摘要
Abstract
In order to visualize the slope deformation and infiltration process,indoor model tests were conducted by using transparent soil principle and digital photogrammetry technology,focusing on the analysis of slope infiltration under rainfall infiltration and two types of transparent soil slope instability modes for slopes containing preferential flow paths and normal slopes.The results show that the infil-tration process and slope deformation can be visualized with the help of digital photogrammetry technology.The normal slope is dominated by vertical infiltration in unsaturated seepage,and oil accumulation is generated at the foot of the slope.In the slope with priority flow path,the pore fluid infiltrates faster at the top of the slope and next to the priority seepage channel,and the wetting front process is acceler-ated,and oil accumulation does not occur at the foot of the slope.The final damage modes of the normal slope and the slope with priority flow path are circular and linear respectively.关键词
