On Prediction Of Soil Erosion By Water In Highway Engineering

Soil erosion is one of the most important ecological environment problems that mankind have to confront. It is related with the rational exploration, usage and protection of water and soil resources in mountainous areas, high lands and the areas full of sand blown by wind; related with the utility and punishment of river and lake. So it is a very important factor that influences the development of an area.Water and soil erosion resulted by constructing highway projects is another important form of water and soil erosion, which seriously affects the peripheral ecological environment, and is related with the feasibility, cost and longevity. It is no time to delay to study the peculiarity and the rule of water and soil erosion resulted by highway projects, and the way of forecast.According to the result of questionnaire, the field experiment in typical earth's surface of yuanmo highway yanping highway and so on are designed to study the rule of water and soil erosion . On the analysis and compare, find a way on prediction of soil erosion by water in highway engineering.On the basis of analyzing the result of field experiment and field survey, the characteristic of water and soil erosion in highway projects is linear moment and acute. The way on prediction of soil erosion by water in highway engineering is analogy. In the last, present the modulus of soil erosion by water in the slopes of highway project. The study will fill up the blank of water and soil erosion.
