【摘要】 高速公路不仅推动了我国经济的发展,而且给人类的生活带来了极大的方便。然而,高速公路建设也会引起水土流失以及生态环境的破坏。论文对街良高速公路建设项目施工期的水土流失进行了分析并对公路建设期间新增的水土流失量进行了预测。选择了美国通用土壤流失方程预测了公路施工期工程占地的新增土壤流失量。经预测,施工期新增的水土流失总量为81.2×103t。然后根据项目建设自身的特点,对项目区的水土流失进行分区防治,并且分别提出相应的防治措施,这些水土保持措施实施后,预计能控制115.8×103t的土壤的流失。更多还原

【Abstract】 Highway has not only promoted the economic development of China, but also brought about prodigious convenience to our daily life. However, highway construction will produce problems such as soil erosion, water loss and destroying of the natural environment. The article analyses the soil erosion, water loss in the construction of Jieliang highway, and forecasts the new loss of the soil in the construction period. The America Universal Soil Loss Equation (USLE) is chosen to forecast the soil loss in construction area. Through calculation, it is anticipated that the new soil loss in construction period is 81.2×103t. According to the characteristics of the project, the construction region is plotted into several areas with corresponding prevention measures for each area. It is expected that 115.8×103t of soil loss can be controlled after the corresponding prevention measures have been implemented.更多还原
