以广西上林县澄江河流域水土保持沟道工程中挡土墙工程和拦沙坝工程为研究对象,根据水土保持沟道工程的设计标准,分别研究挡土墙和拦沙坝工程的设计标准和断面尺寸设计及其稳定性。结果表明,挡土墙和拦沙坝的抗滑稳定系数和抗倾覆稳定系数均大于允许值,能够满足抗滑稳定和抗倾稳定的要求,可以作为该流域沟道工程的施工提供参考和借鉴。挡土墙和拦沙坝可以减少土壤流失量6.30×104t,保护流域中下游的耕地254hm2,在带动剩余劳动力就业、保障农业生产创收等方面实现水土保持工程效益。

In the study of abamurus and sediment storage dam projects in water and soil conservation of Cheng Jiang river basin,Shanglin,Guangxi,the design standard,size and stability of cross section in abamurus and sediment storage dam projects are studied according to the standard of channel engineering design of water and soil conservation.The results show that both the stability coefficient of sliding and inclining prevention in abamurus and sediment storage dam projects are higher than the allowed value,which indicates the projects can satisfy the requirements in the stability of sliding and inclining prevention,and also be the reference for channel engineering construction in this river basin.By the abamurus and sediment storage dam projects,the volume of soil loss can decrease 6.30×104t and the protected cultivation land in the middle and low of river basin is 254hm2.The benefit of water and soil conservation can be reflected by the increase of surplus labor employment and guarantee the revenue from agricultural production.
