| 摘 要： | 兰州城区地质环境条件复杂,对地质环境扰动的人类建设工程活动强烈,引发城市南北两山斜坡区段地质灾害频发。对地质灾害分布规律和发育特征分析后认为,地形、岩土体类型、地质构造是崩塌、滑坡灾害发生的控制因素,降水和人类工程活动是崩塌、滑坡灾害发生的主要引发因素。

| Abstract: | Human construction activities in Lanzhou city triggered the continual occurrence of geological hazards in the slope area of the north and the south mountain along Lanzhou city.The analysis of distributution and development of hazards show that the terrain,rock and soil types,geological structures are the key control factors to cause the collapses and landslide happened in Lanzhou city,meanwhile,precipitation and hunman activities are the induced factors. |
