| 摘 要： | 山区公路工程由于线长、工程量大,施工期可能引起比较严重的水土流失。在编制公路工程水土保持方案时,需要对水土流失量进行预测。公路沿线原地貌水土流失量及新增水土流失量之和即为全部的水土流失量。公路沿线原地貌水土流失量可以采用平均侵蚀模数法及通用土壤流失方程式进行预测,新增水土流失量由扰动地表和工程弃堆渣引起的水土流失量组成。最后,通过具体的工程,对山区公路工程建建设期水土流失量的预测模式进行了实证。

| Abstract: | The highway project in mountainous area will lead to serious soil erosion,due to its long road line and large volume of the work.While the program of water and soil conservation is drawn up,the prediction of the amount of soil erosion is needed. The whole amount of soil erosion comprises primary and new soil erosion amount. The primary soil erosion amount may be predicted by the method of average erosion modulus or universal soil loss equation.The new soil erosion amount is made up of erosion amount due to disturbed earth surface and discarded soil.Finally, the prediction model of soil erosion amount about a specific highway project during its construction period in mountainous area is analyzed. |
