高速公路建设项目属线型工程,一般路线较长。公路沿线遇到山体、沟道、河流要开凿隧道或架设桥梁等工程节点;穿越不同的地貌类型产生自然节点;跨域不同的行政区域产生行政节点。以呼和浩特-集宁高速公路为例,对高速公路水土保持方案编制中的三种节点的控制作用展开分析研究,能准确把握水土保持方案编制过程中的土石方平衡,防治分区及防治体系确立,补偿费征收额度,对高速公路水土保持方案的编制具有较强的指导意义。
Expressway construction project is a linear project, the general route is longer. Highway along the mountain, channel, river to dig tunnel or erection of bridges and other engineering nodes; through different types of geomorphology produce natural nodes; different administrative regions across the administrative node. Taking Hohhot-Jining Expressway as an example, this paper analyzes and analyzes the control effects of three kinds of nodes in the program of soil and water conservation of expressway, accurately grasps the earth-rock balance in the process of soil and water conservation plan preparation, establishes prevention and control zoning and prevention and control system, The amount of fees levied on the Expressway water and soil conservation program has a strong guiding significance.
