中文摘要 | 地工合成材的快速發展有一大部份的原因歸諸這些材料在廢棄物掩埋場中的應用 。由於法規的制訂直接導致了地工止水膜的廣泛使用,其後許多其他地工合成材料也陸續被 引進掩埋場工程中。但是也因為法規的限制,導致了許多新開發的地工合成材料並不容易被 立即應用於掩埋場中;主管機關往往必須針對個案進行材料的評估。近幾年來,美國衍生出 一套基於技術相當性的評估方式,非常值得借鏡;本文中將予以詳細說明。文中雖僅就掩埋 場中最重要的子系統 - 阻水系統使用的材料為例做詳細的技術相當性評估介紹。 但是這一 套原則對於其他子系統如滲出水集排水系統 (Leachate Collection and Removal System, LCRS)、排氣系統 (Gas Collection System)、甚至是每日覆土 (Daily Cover), 都同樣適 用。 |
英文摘要 | Hydraulic barrier is the most critical component of the bottom lining and final cover systems of modern landfills. There is a wide variety of materials that can be used for hydraulic barriers including synthetic materials made of polymers, natural soils, asphalt, and composites made of some of these materials. The choice of materilas has been limited by regulations such that many new geosynthetic products are excluded. Recently, as method for comparing these materials based on technical equivalency has been developed and has been gaining acceptance among the regulatory agencies and the industry. The procedure will be introduced in this paper and will use the hydraulic barrier material as the subject for evaluation. The procedure should also be employed to evaluate other components of the landfill. |
