摘要

研究高速路边坡土壤水分含量及其动态对选择适宜的植物种类，提高边坡稳定性具有重要意义。采用定位取样法研究了陕蒙沙漠高速公路路堤和路堑边坡土壤水分的季节变化。结果表明，路堤和路堑边坡土壤水分具有明显的季节变化规律，其中5-6月土壤含水量较高，7-9月较低，10-12月期间土壤水分逐渐恢复;路堤和路堑边坡土壤含水量的垂直分布表现为表层土壤含水量最低，随着土层深度增加，土壤含水量逐渐增加，路堤边坡各层土壤含水量高于路堑边坡。

Abstract

Study of soil moisture content and its dynamics on road slope is important to choose appropriate plant species for bio-engineering re-vegetation and improve slope stability. Soil moisture content and its dynamics on road embankment and cutting desert expressway. Results showed that soil moisture content on embankment and cutting slope had the typical seasonal dynamics.Soil moisture was higher during May and June

while it was lower during July and September and resumed gradually during October and December. Vertical distribution pattern ture content was the lowest in surface soil layer. Soil moisture content increased with increased soil depth and it was higher on road embankment than cutting slope.
