摘要:
透水铺装是常用的低影响开发技术之一，具有调控径流、补给地下水等功能。为深入了解透水铺装的水文转化过程、识别水文转化规律，借助蒸渗仪等设备监测降雨、土壤水分、深层渗漏、砾石层出流与蒸发过程。在天然降雨和人工降雨两个监测时间序列中，砾石层仅在降雨强度为98 mm/h的人工降雨中产生出流，表明透水铺装的径流削减效果良好。天然降雨和人工降雨条件下深层渗漏量分别占降雨损失的75%和91%，深层渗漏是透水铺装主要的水分损失项，透水铺装截留的大部雨水通过下渗回补地下水。位于换土层的2层监测土壤，其含水率变化较一致，且对降雨的响应较强；而位于原状土层的3层监测土壤，对降雨的响应随着土壤埋深的增加而降低。
Abstract:
Permeable pavement is one of the commonly used low impact development technologies, which can regulate runoff and replenish groundwater. This paper monitored the rainfall, soil moisture, deep seepage, gravel outflow and evaporation by means of lysimeter and other equipments, so as to deeply understand the hydrological transformation process and identify the hydrological transformation law of permeable pavement. In the two monitoring time series of natural rainfall and artificial rainfall, the gravel layer only produced outflow in the artificial rainfall with intensity of 98 mm/h, indicating that the runoff reduction performance of permeable pavement was good. Deep seepage in natural rainfall and artificial rainfall accounted for 75% and 91% of rainfall loss, respectively. It was the main water loss item of permeable pavement, and most of the rainwater intercepted by permeable pavement seeped back to replenish groundwater. The moisture content of the monitored soil in the two layers of the replaced soil layer was consistent, and the response to rainfall was strong. However, the response to rainfall of the three monitoring soil layers in the raw soil layer decreased with the increase of soil depth.
