山区高速公路建设期水土流失特点概述

摘要

以重庆地区梁忠高速公路为例,根据工程项目所处的山区自然地理特点,通过实地调查和现场量测,从侵蚀环境角度出发,结合山区地质环境的特殊性,系统分析山区高速公路建设中水土流失发生的侵蚀动力、侵蚀单元及侵蚀对象的特殊性,总结重庆市山区高速公路建设期水土流失特点,以期为山区高速公路建设过程中,划分防治水土流失的责任范围、预测水土流失以及布局水土保持措施等提供理论依据.%Based upon Liangping-Zhongxian Expressway in Chongqing,according to natural geographic characteristics of the mountainous area where the project is located,this paper,through site survey and reconnaissance,in view of environment erosion,with integration of specialty of the geological environment in mountainous area,analyzed the specialties of erosion power,erosion unit and erosion object occurred during soil and water loss in construction of mountainous expressway,so to summarize the characteristics of soil and water loss in construction of mountainous expressway in Chongqing.It is expected to provide theoretical basis for classify responsibility range of soil/water loss prevention,forecast soil/water loss and arrange soil/water retain measures,etc.during construction of mountainous expressways.
