摘要：
废弃露天矿山存在地质灾害? 生态破坏等一系列地质环境问题? 笔者以无锡市滨湖区某崩塌地 质灾害生态治理工程为例, 探讨了以预应力锚索? 钢绳锚杆 + 主动防护网以及被动防护网等措施彻底 消除地质灾害隐患的应用效果, 同时深入研究了基于客土喷播? 生态袋铺设? 高分子固化剂补喷等方 法的高陡岩坡生态修复技术? 实践表明, 锚索等工程措施稳定提升坡体安全系数, 高分子固化剂等生 态修复措施使坡面植被覆盖率由 10% 提升至 85% 以上, 项目成效显著, 可为类似工程提供参考? |

Abstract:
There are a series of geological environmental problems such as geological disasters and ecological damage in abandoned open?pit mines. Taking a geological disaster ecological control project in Binhu District of Wuxi City as an example, the authors discuss the application effect of prestressed anchorage, steel rope anchor + active protective net and passive protect net to completely eliminate the potential risk of geological disasters. Mean? while, the ecological restoration technology including high and steep rock slope based on the methods of external? soil spray seeding, ecological bag laying and polymer curing agent spraying is studied. Practice shows that engi? neering measures such as anchor cable can improve slope safety factor, ecological restoration measures such as poly? mer stabilizer may increase slope vegetation coverage from 10% to more than 85% . The project has remarkable re? mediation effects, and can provide useful reference for similar projects.
