高河矿铁路专用线工程位于长治县、长治市郊区及长子县境内。项目区地貌类型为北方土石山区的冲积平原区。铁路专用线沿线所经地貌单元为侵蚀堆积型河流浊漳河水系的河道、河漫滩及两侧的一、二级冲洪积阶地平原。文章结合高河矿井工程铁路专用线项目组成、工程区自然概况、工程施工工艺,分析了项目建设过程中和自然恢复期水土流失形式及危害,为工程水土流失防治及监测提供了科学依据。 Gahe Mine railway line project located in Changzhi County, Changzhi City suburbs and the territory of the Yangtze River. The landform of the project area is the alluvial plain area in the northern mountainous area. The geomorphic units along the railway line are eroded rivers and floodplains of riverbed Zhangzhu River and the first- and second-level alluvial terrace plains on both sides. Based on the composition of the special railway line of Gaohe Mine Project, the natural condition of the project area and the construction process, the paper analyzes the forms and the hazards of soil and water loss during the project construction and the natural recovery period, and provides a scientific basis for the prevention and control of soil and water loss.
