摘要
三清山风景区内地质灾害类型为崩塌类的崩塌、危岩体及落石,主要分布在陡坡、陡(悬)崖或石柱部位。预测区内工程切坡稳定性中等至好;地基稳定性除上站和19号支架点较差外,其余较好至好;工程施工对风景区内的“女神峰”、“巨蟒出山”二重要景点稳定性影响小。预测认为索道工程建设引发或加剧及工程建设本身遭受地质灾害总体危险性中等,19号支架点遭受地质灾害危险性大。拟建场地作金沙客运索道工程建设用地基本适宜。
This paper describes the distribution, types and characteristics of geological hazards, particularly its genesis based on the complex degree of geo-environment along the passenger cableways and its neighboring area. The geo-environment condition in the ongoing construction area belongs to the complex type. There exist some geological hazard types such as rockfall, collapse and dangerous rock body happened with moderate frequency in the area of ongoing passenger cableways. There is little possibility of debris flow in the valley. As a whole, the stability of natural slopes is good. Geological hazard bodies are steep slopes, cliff and rock pillar. The present geological hazard conditions are moderate. The stability of constructed slopes is moderate or good. The base stability is relatively good except Shangzhan and Support 19. Constructions have less effect on the stability of Nushenfeng and Jumangchushan scenic spots. Construction waste earth and stones have less impact on environment. It is considered that the dangers induced or exacerbated by passenger cableways construction and its suffered dangers are moderate. The dangers of Support 19 affected by geological hazards are great. The area of interest is basically fit for the field of planning to construct Jinsha passenger cableways.
