- 摘要:
- 在沟壑治理工程布置过程中，存在着单纯拦截、贮蓄的现象，缺乏完全理论研究与指导。甚至水土保持技术文件也存在片面性，导致基层实施单位“年年筑坝年年垮、数量升级无实存”。根据伯努里能量守恒定律，工程布设应分为抬高侵蚀基点Z2与降低侵蚀源点Z1两种途径。为此引进跌水坝概念。提出在沟壑治理中，不可片面强调“抬或降”，应将抬高侵蚀基点与降低侵蚀源点有机配合，科学地将沟道分割成若干的水力平衡断面，上有跌水坝控制下切护床底，下有谷坊坝拦蓄水土可造田。这样，沟壑治理必然收到事半功
- Abstract:
- There is a lack of theoretical research and guidance and a phenomenon of simply retaining water in gully control engineering distribution, and even one sidedness in technical documents of soil and water conservation.These led to collapse in dam every year.According to the Bonuli law of conservation of energy, there are two ways to the engineering distribution, that is, to raise the erosion base point Z2 and to lower the erosion source point Z1, therefore, the concept of drop dam was introduced.In gully control engineering works, some measures should be adopted at the same time, such as combining the raise of erosion base point and there is the lower of erosion source point, scientifically dividing the gully into a certain number of hydraulically equilibrium section, and there is the drop dam in upper reaches to control and protect gully, and check dam in lower reaches to retain soil and water to make farmland.
