摘  要:
以20世纪50年代修建成昆铁路时形成的路堑边坡为对象,对道路边坡土壤水分在不同坡度、坡长、坡位的空间变异性进行观测研究。结果表明:道路边坡土壤水分随着坡度的增大呈现先增大再减小的变化趋势,在同一坡面不同坡位上的土壤含水量表现为坡下>坡中>坡上。道路边坡土壤水分随着坡长的增长而减小,最短的10 m坡长土壤含水量为23.27%,而最长的40 m坡长土壤含水量为21.78%,最短坡长比最长坡长的土壤含水量增加了6.84%。

摘  要:
Based on the railway slope which formed by the building of Chengdu-Kunming railway,the variability of soil water moisture of the road-slope in different slope steepness,slope length and slope position were observed and studied.The results showed that:the soil water moisture has the tendency of increasing at first,and then decreasing with the increasing of slope steepness.The sequence of the magnitude of the heterogeneity is the bottom-slope> the mid-slope>the top-slope along the same slope.Soil water moisture decreases with the increasing of the slope-length:the shortest(10 m) is 23.7%,and the longest(40 m) is 21.78%,the soil water moisture of the shortest slope is as 1.068 4 times as that of the longest slope.
