| 摘 要： | 我国交通建设项目的环境评价已经开展了多年,其中施工期水力侵蚀加速系数法已在现有水土保持方案的编制工作中使用.本文对铁路工程环评中的加速侵蚀系数法进行阐述,采用USLE模型参数进一步分析、重点探讨铁路建设施工期各参数的取值和计算.根据工程特点,得出平原和丘陵地形、不同路基填料和不同土壤条件下铁路施工期水力侵蚀加速因子参考表.

| Abstract: | The environment evaluations concerning transportation infrastructure constructions have been carried out for ages in China.The accelerated quotient methods have been applied in a great many circumstances.This paper discusses accelerated quotient methods by analyzing the USLE model,and casts light on how to select and compute parameters in railway constructions.As a conclusion,this paper makes into a list the accelerated water erosion quotients of the slope and plane part during railway constructions,including different basement padding and distinct soil conditions on the basis of the railway construction characteristics. |
