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。
Taking the retaining wall and the barrage project in the soil and water conservation channel project of Chengjiang River Basin in Shanglin County, Guangxi as the research object, according to the design standards of the soil and water conservation channel project, the design standards of the retaining wall and the barrage project And section size design and stability. The results show that both the anti-sliding stability coefficient and anti-overturning stability coefficient of the retaining wall and the barricade retaining bar are both larger than the allowable values, which can meet the requirements of anti-sliding stability and anti-tilting stability, which can be used as a reference for the construction of channel engineering in the basin. . Retaining walls and barricades can reduce the amount of soil loss by 6.30 × 104t, protect 254hm2 of farmland in the middle and lower reaches of the river basin, and achieve benefits of soil and water conservation in driving employment of surplus labor force and ensuring agricultural production income.
