摘要
针对大中型水库移民后期扶持项目靠山渠道的水土治理问题,通过改变渗流路径,设计内置多种不同内部孔隙结构填料的变渗径多骨料生态砼护岸.结果显示,水土流失治理度比标准值提高2%,渣土防护率较标准值提高 1%,表土保护率较标准值提高 1%,林草植被恢复率与林草覆盖率较标准值分别提高 1%和 3%.研究方案解决了渠道渗水和边坡坍塌的问题,对减小渠道水土流失作用明显,具有一定的技术可行性和经济可行性.
Abstract
In order to solve the problem of soil and water control in the back-up channel of the support project in the later stage of the migration of large and medium-sized reservoirs,by changing the seepage path,the multi-aggregate ecological concrete revetment with a variety of internal pore structure fillers was designed.The results showed that the treatment degree of soil erosion was 2% higher than the standard value,the residue protection rate was 1% higher than the standard value,and the topsoil protection rate was 1% higher than the standard value.The vegetation restoration rate of forest and grass and the coverage rate of forest and grass increased by 1% and 3% respectively.The research has solved the problems of seepage and slope collapse in the channel,and has obvious effect on reducing soil and water loss in the channel,and has certain technical and economic feasibility.
