京西山区地质条件复杂,小窑浅层采空区灾害频繁,对地区工程建设及生态环境造成了严重影响和损失。小窑采空区主要灾害类型为地面塌陷及由其诱发的崩塌、不稳定斜坡和泥石流等地质灾害,灾害活动有着隐蔽性、突发性及随机性的特征,受地质构造、地层岩性、地形地貌以及气候条件、人类活动等内外地质作用因素影响,又表现出一定的客观规律。本文通过分析京西山区小窑采空区灾害特征和致灾因素,以便于开展针对性的防范措施,希望能为京西山区工程建设提供一些参考和帮助。
The geological conditions in the western Beijing mountainous area are complex, and the shallow mined-out areas in the small kiln are prone to disasters, which seriously impact and damage the regional engineering construction and ecological environment. The main disaster types in the gob of the small kiln are ground collapse and the induced geological disasters such as the collapse, the unstable slope and the debris flow, and the disasters have the features of concealment, suddenness and randomness. Due to the geological structure, stratigraphic lithology, Terrain and climate conditions, human activities and other internal and external geological factors, but also showed some objective laws. In this paper, by analyzing the disaster characteristics and disaster-causing factors of the small kiln-gob area in west mountainous area of Beijing, in order to carry out targeted preventive measures, I hope to provide some reference and help for the construction of mountainous area in western Beijing.
