中文摘要：

联合一个网状的盲目排水系统和一个垂直层次排水系统的特征的一种新奇的水控制技术被开发并且在 Yanziyan 清洁的垃圾堆适用，它在一个区域被定位(Loudi 城市，湖南省，中国) 与高降雨和高地下水水平。当阻止地下水的瓦解的流动时，网状的盲目排水管系统，在底部和垃圾堆地点的方面墙上被安装，能方便地从这个地点指导地下水的流动。垂直层次排水系统被安装在垃圾堆地点分开降雨水和 leachate，高效地因此减少 leachate 处理的压力。整个排水系统由渗出物控制和分离并且在降雨水的立刻的排水在基础稳定起一个关键作用。排水技术的 leachate 减小效率以前以 leachate 生产被计算(336519 m ³) 并且在以后(29664 m ³) 技术申请。从降雨水和地下水流入导出的超过 90% leachate 在垂直层次排水和网状的盲目排水系统的安装之上被避免。技术能因此在与高降雨和高地下水水平位于区域的垃圾堆被推广并且申请水控制。建议技术能被用来减轻 leachate 处理的压力并且减少不稳定性的风险。

英文摘要：

A novel water control technology that com- bines the features of a reticular blind drainage system and a vertical hierarchical drainage system is developed and applied in the Yanziyan Sanitary Landfill, which is located at an area （Loudi City, Hunan Province, China） with high rainfall and high groundwater level. The reticular blind drain system, which was installed on the bottom and side walls of the landfill site, can conveniently guide the flow of groundwater out of the site while preventing a disorga- nized flow of groundwater. The vertical hierarchical drainage system was installed to separate rainfall water and leachate in the landfill site, thus efficiently reducing the pressure of leachate treatment. The whole drainage system plays a key role in foundation stabilization by seepage control and separation and in the instant drainage of rainfall water. The leachate reduction efficiency of the drainage technology was calculated in terms of leachate production before （336519 m3） and after （29664 m3） technology application. Over 90% of leachate derived from rainfall water and groundwater inflow was avoided upon installation of the vertical hierarchical drainage and reticular blind drainage systems. The technology can thus be popularized and applied for water control in landfills located in areas with high rainfall and high groundwater level. The proposed technology can be used to alleviate the pressure of leachate treatment and to reduce the risk of instability.
