| 摘 要： | 黄土塬区提灌工程保证了农业生产，却造成了地下水位大幅抬升，使得近年来黄土台缘滑坡不断发生。黄土滑坡一个普遍特征就是后缘发育地裂缝以及落水洞，使地表水（灌溉水以及降雨）直接灌入坡体，诱发了大量黄土滑坡。因此，地表水入渗对于黄土滑坡机理研究以及滑坡防治具有重要意义。文章基于对陕西泾阳南塬黄土滑坡的现场调查，对黄土台缘滑坡地表水入渗工程地质问题进行了初步分析，包括：①地表水入渗与落水洞形成机制；②地表水入渗途径及其与黄土滑坡发育过程的关系；③降雨因素对于黄土滑坡的影响程度。

| Abstract: | Irrigation is essential to the agricultural basis of the loess region economy ; however, it has resulted in lots of loess landslides in recent years. The development of terra-fissures or sink holes is very significant and prior to loess landslides. So studying the surface water infiltrating is important for the forecast and control of landslides. And based on field-walk surveys for loess landslides in South Terrain, Shanxi Province, some primary conclusions are presented here, including： ①relation between surface water infiltrating and sink holes developing mechanism; ②the significance of vertical joints, terra-fissure and sink holes to surface infiltrating; ③effect of rain fall on loess landslides occur. |
