摘　　要：为了研究热带多雨地区超深厚土质高边坡生态修复设计,以海南省迈湾水利枢纽工程主坝左岸220 m土质边坡为例,结合当地水文地质条件和特点,反演分析了地质参数。基于生态修复目的,提出了地表排水、锚索和排水洞等治理措施,分析了各治理措施的安全敏感性。选择了“坡面排水+9排锚索”的治理方案,实现了深厚土质高边坡治理和生态修复,且具有经济合理性。研究成果可为中国热带地区土质超高边坡的治理和生态设计提供借鉴。To explore the ecological restoration design of deep thick and high soil slope in rainy tropical area,taking the 220 m slope at the left bank of the main dam of Maiwan Hydraulic Project in Hainan Province as an example,on the basis of the local hydrogeological conditions and characteristics,the inverse analysis of the geological parameters was conducted.By considering the ecological restoration,the treatment measures such as surface drainage,anchor cable reinforcement and drainage tunnel etc.were put forward.The safety sensitivity of each treatment measure was analyzed.The economic and feasible scheme of surface drainaging and 9 rows of anchor cable was designed to realize the ecological restoration of deep thick and high soil slope.It can provide reference for the treatment and ecological design of super-high soil slope in tropical areas.
