| 摘 要： | 为了探索生态覆盖系统的合理设计,利用非压实覆盖土层储蓄降水、依靠植物的蒸腾和土壤蒸发消耗土壤水从而控制渗沥污染,在武汉大学灌溉排水与水环境综合试验场开展了不同组合覆盖形式的渗沥控制试验,并对生态覆盖系统进行非饱和水运动数值模拟和水量平衡分析,结果表明,适合于生态覆盖的土壤类型为壤土和粘壤土,覆盖土层填筑密度宜在1.1-...

| Abstract: | Conventional cover systems of waste landfills rely on barrier layers made of compacted clay,geosynthetics and geomembranes,either alone or in combination.Although barrier-type cover systems are sometimes described as impermeable,in practice it is intend to fail due to subsidence caused by waste decay,water and wind erosion,wet-dry cycles,freeze-thaw cycles,ultraviolet degradation and intrusion by burrowing animals.An ecological cover system consists of a uncompacted soil layer covered by native plants,which... |
