排水管

Through combining the three moisture movements of leachate seepage in drainage layer, leackage through liner and pipe flow in perforated drainpipes, a leachate hydrological mechanics model is established. This thesis analyses related parameters of LCS according to model results and offers a practical calculation method for landfill LCS design.

在考虑渗滤液在排水层中的渗流，渗滤液通过防渗衬垫的渗漏以及渗滤液在穿孔排水管中的管道流的基础上，建立了渗滤液水动力学模型，根据模型分析结果对渗滤液收集系统相关参数进行了分析，提出了适宜于填埋场渗滤液收集系统设计的计算方法。
