| 摘 要： | 通过对海州矿滑坡因素的统计分析，得出降雨及地表水入侵诱发滑坡27次，其稳定性影响因素位居第二。在此基础上，建立了海州矿某断面的数学模型，并对边坡地表入渗的规律进行了研究，得出了边坡在降雨及地表入渗过程中基质吸力的变化规律以及水压力的分布、变化规律，有利于更好地了解地表入渗影响下的边坡失稳机制。

| Abstract: | To understand subsoil water level changing in the rainfall process has vital significance on stability of slope. In the article, through statistical analysis of the Haizhou pit landslide factors, we found that rains and the surface water invasions have induced 27 landslides, which stand in second place in factors. On this foundation, we established a mathematical model of a cross section in Haizhou pit, and studied slope surface infiltration rule. Thus we obtained changing rule of matrix suction, distribution and changing of water pressure in slopes. And results shows that surface infiltration will bring harmful influence on the stability of rock slope,this can provide us for understanding better to the landslide mechanism of rock slope under the influence of surface infiltration. |
