- 摘要:
- 在分析燕子河流域地质灾害形成的地质环境背景及诱发因素的基础上，对燕子河流域崩塌地质灾害的类型、发育特征进行了分析，总结了流域内3种主要的崩塌地质灾害破坏模式及演化过程，并选取典型崩塌进行了稳定性研究。结果表明：燕子河流域崩塌地质灾害以岩质、小型、复合式、中低位、不稳定崩塌为主；崩塌在空间上主要分布在燕子河干流、主要支流河谷斜坡地带及康县—阳坝公路沿线人类工程活动密集的“一路一带”上，时间上主要集中于降雨较为集中的7—9月；崩塌的破坏模式主要有碎裂—坠落式、弯折—倾倒—滑移式、碎裂—滑移式，每种破坏模式经历4个阶段演化后形成灾害；典型崩塌稳定性计算得出暴雨是崩塌发生的主导诱发因素。
- Abstract:
- In the analysis of the geological environment background and geological disaster inducing factors of the Yanzi River Basin, the geological disaster type and the Yanzi River Basin development characteristics were analyzed, the three major failure modes of collapse and evolution process were summarized, and the typical collapse was selected to analyze stability. The results show that the collapse geological disasters of Yanzi River Basin were the rock, small, composite, low and unstable collapse; collapse mainly distributed in valley slope zone of the Yanzi River and the main tributary, Kangxian County—Yangba town road of human engineering activities ‘area all the way’, collapse focused on the more concentrated rainfall events from July to September; the main failure modes of collapse are fracturing-load falling, bending—toppling—sliding and fracturing—sliding, each failure mode experiences disaster after four stages of the formation of evolution; the typical calculated collapse stability indicates that rainstorm is the dominant factor inducing collapse occurrence.
