| 摘 要： | 西藏地区公路建设过程中的水土保持一直以来是必须面对的机遇与挑战。文章以国道318线通麦段公路改建项目为例,对工程施工造成的土壤侵蚀类型和强度进行了预测分析。根据实地调查,项目区可划分为主线防治区、病害整治防治区、施工场地、取料场、弃渣场5个区域,文章分别对其扰动地表而可能产生的水土流失量进行了预测。结果显示预测期内工程水土流失总量约10 990 t,其中弃渣场、路基边坡流失量较大,应属于水土流失的重点防治区。

| Abstract: | Water and soil conservation during highway construction in Tibet is always a challenge and chance must be face to.This article is based on State Road 318 Tongmai section highway reconstruction project.It predicted and analyzed the type and intensity of soil erosion caused by the construction.According to field surveys,the project area can be divided into five regions: main road control line,disease prevention and treatment area,construction sites,material site and spoil ground.The article predicted the soil erosion amount causing by disturbance effect of construction on such five regions respectively.The results showed that the total amount of soil erosion is about 10 990 t,which spoil ground and embankment slope assumed larger loss.These places should belong to the special control areas of soil erosion. |
