| 摘 要： | 为解决现行水平截流沟设计方法缺乏合理性和系统性的问题,从理论分析入手,给出坡地水平截流沟的系统设计方法和具体的计算公式。用植被或树木的耗水量结合当地一定保证率下的降雨量作为主要因素确定水平沟的距离;用当地设计保证率下最大一次可能降雨量、最大降雨强度、土壤入渗速率等参数确定水平沟断面尺寸———当量宽度与深度。实际工程应用结果说明利用文中给出的方法和公式进行坡地水平截流沟的设计是可行的,与以往的经验方法相比,该方法更具合理性、可靠性,可应用于生产实践。 |

| Abstract: | In order to solve the problem of absenting rationality and system-on design method of level ditch of runoff harvesting, based on theory analysis, the systematic design methods and calculated formula were put forward. The distances between ditches were decided by the water requirement of local vegetation combining with the designed potential rainfall amounts. The equivalent width and depth were estimated by the maximum potential rainfall amount during a storm even of the locality, the highest rainfall intensity and the soil infiltration rate and etc. factors. The feasibility of the method of level ditch of runoff harvesting was demonstrated by the practical engineering application. Compared with traditional design methods, this method was more rational and reliable, could be applied wildly. |
