汾河下游古交段河道治理工程水土保持措施

Water and soil conservation measures in river regulation project of the lower reaches of Fenhe River in Gujiao City,Shanxi Province

河道治理工程在扩大行洪能力、提高区域防洪标准的同时,改善河道沿线的生态环境.但其施工过程会涉及土方的开挖、回填,造成一定程度的水土流失.本文以汾河下游古交段河道治理工程为例,通过分析该工程水土流失现状及其影响因素,进行项目区土壤流失量预测,在此基础上,提出因地制宜、因害设防的水土保持措施布设和监测方案,并进行其效益分析,可供相似工程建设参考.

The river control project improves the ecological environment along the river while expanding the flood discharge capacity and improving the regional flood control standard.However,the construction process will involve the excavation and backfilling of soil,resulting in a certain degree of soil and water loss.This paper takes the river control project of Fen River in Gujiao City,Shanxi Province as an example,through the analysis of the current situation of soil and water loss and its influencing factors,carries out the vector prediction of soil loss in the project area,and on this basis,puts forward the layout and monitoring scheme of soil and water conservation measures according to local conditions and fortification due to damage,and carries out the benefit analysis,which can be used as a reference for the construction of similar projects.
