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, the collapsing and rockfall geological disasters occur frequently in the hilly area of western Liaoning. The geological disasters caused by the collapse of the Daohugou Village in Qazuo County are the typical rockfalling and collapsing landslides in the lower slope of the upper steep cliffs. The common protective structures of collapse and geological disasters in western Liaoning are mostly masonry structures. There are many shortcomings in masonry structures. Comprehensively considering the geological and environmental conditions of the collapse of the Taohuogou Village, the characteristics of the collapsed geological disasters are analyzed. Through comparison and selection of various control schemes, SNS active protection system and passive protection system jointly used by the management program, through the analysis and calculation to determine the active protection system and passive protection system model. This article provides a reference for the selection of similar collapse geological disaster management options and SNS protection system selection.
