水库消落区土地快速投入使用的渗滤技术初探

从岩土渗流理论出发,以尽快降低表层地下水位,同时也保持一定地下水位为基本原则,研究使水库退水后出露的土地尽快地从过饱和状态转变到适合作物耕种湿度的渗滤措施。提出了井字形排水盲沟的深度、宽度、间距等基本布置参数,结果表明该方法简便、经济、切实可行。

Study on Percolation Technique Putting Land in Use Fast in Degrading Area of Reservoir

From the rock seepage theory, based on the principle of lowering of groundwater level of surface layer as fast as possible and at the same time maintaining groundwater level to a certain extent, this paper discusses the percolation measures to change the land from the super saturation state to the suitable humidity for farming after the depletion of reservoirs, and puts forward the layout parameters of the well-shaped blind ditches of drainage, such as the depth, the width, the span and so on. The results show that the method is simple, economic and feasible.
