辽宁省喀左县道虎沟山坡崩塌地质灾害防治工程设计

HILLSIDE COLLAPSE GEOLOGICAL HAZARD MANAGEMENT ENGINEERING DESIGN IN DAOHUGOU VILLAGE KAZUO COUNTY OF LIAONING PROVINCE

近年来,辽宁西部低山丘陵区崩塌落石地质灾害频繁发生,喀左县道虎沟村崩塌地质灾害为典型的上部陡崖危岩崩落下部斜坡落石滚动崩塌地质灾害。辽西地区常用的崩塌地质灾害防护结构多为圬工结构,圬工结构存在很多缺点,综合考虑道虎沟村崩塌的地质环境条件,分析崩塌地质灾害特征,通过多种治理方案比选,确定采用SNS主动防护系统和被动防护系统联合使用的治理方案,通过分析和计算确定主动防护系统和被动防护系统型号。本文为类似崩塌地质灾害治理方案选择及SNS防护系统选型提供参考。

In recent years, collapse rockfall geological hazard frequently occurred in the hilly areas of western Liaoning. Col- lapse geological hazard in Daohugou village Kazuo county is a typical collapse rockfall geological hazard of upper cliff dangerous rocks falling and lower slope falling rocks rolling. In western Liaoning area commonly used masonry structure as collapse geo- logical hazard protection structure. Masonry structure exist many shortcomings. Comprehensively considering geological condi- tions of collapse geological hazard in Daohugou village, analysising its features, through a variety of governance scheme com- parison and selection, determine using a combined plan of SNS active protection system and passive protection system. Through analysis and calculation, determine type of SNS active protection system and passive protection system. This paper provides a reference for similar collapse geological hazard governance scheme selection and SNS protection system type selection.
