AI Technical Summary
Technical Problem
传统堆石坝下游坝坡通常采用块石护坡或混凝土衬砌等刚性防护结构，虽然能够满足工程稳定性要求，但存在明显的生态环境问题：一方面，硬质化表面破坏了自然植被生长条件，导致坝区生态系统退化；另一方面，料场开采产生的弃渣往往需要单独堆放处理，不仅占用土地资源，还可能引发水土流失等环境问题
Benefits of technology
本申请中，该兼顾生态环境保护的堆石坝布置结构通过在堆石坝的下游设置由覆土和/或料场弃渣构成的覆盖层，有助于进行绿色处理弃渣，从而以较低的成本代价，达到改善、保护当地生态环境的目的，在覆盖层上设置的生物多样性热点区，能够提升植被恢复效果，使植物覆盖率提高；此外，覆盖层底部的排水层与堆石坝排水体衔接，一方面可不受坝后覆土或弃渣的制约，排出坝体渗水；另一方面还可抵挡坡脚处往复水流作用，排出下游坝面或覆盖层中的渗水；生态过渡层可增强土壤活性，提高生态系统稳定性。

Abstract
The application relates to a rockfill dam arrangement structure considering ecological environment protection, which comprises a rockfill dam and a covering layer. A transition layer and a geotextile are arranged on the downstream side slope surface of the rockfill dam. The transition layer comprises transition material laid on the downstream side slope surface of the rockfill dam and an ecological transition layer laid on one side of the top of the transition material. The geotextile is laid flat on the downstream side slope surface of the transition layer. The covering layer is arranged on the downstream side of the geotextile. The covering layer has a preset laying thickness and a preset downstream slope. The covering layer is topsoil and / or yard waste. A plurality of biological diversity hot spot areas are arranged on the covering layer at intervals. The biological diversity hot spot areas are filled with at least one of local plant seeds, water-retaining agents and microbial agents. The surface of the covering layer is covered with a degradable anti-scouring net. The bottom of the covering layer is provided with a drainage layer. The upstream side of the drainage layer is connected with the drainage body of the rockfill dam. The rockfill dam arrangement structure can meet the dual requirements of engineering safety and ecological protection.
