摘要
贵州省地处山区,是崩塌地质灾害的易发区及高发区。据贵州省88个县(市、区)重点地区重大地质灾害隐患详细调查数据统计,拉裂式崩塌占全省崩塌总数第二位。本文针对贵州省拉裂式崩塌的特点,从地理位置、地形地貌、地层岩性、地质构造、破坏过程、形成机理等方面总结其分布特征及发育情况,并结合贵州拉裂崩塌某一实例通过稳定性计算及数值建模两种方法分别对其稳定性进行了理论分析。
Guizhou Province is located in mountainous area, where geological hazard of collapses are prone to occur. According to the key areas＇detailed major geo-hazard survey statistics in 88 counties of the province, crackstyle collapse ranks the second among the total collapses. Guizhou Province crack-style collapse features in geographical location, topography, lithology, geological structure, the destruction process were explored; its formation mechanism of distribution was summarized. And specific combination of a Crack-type Collapse instance of Guizhou stability calculation and the stability of two numerical modeling methods were analyzed theoretically.
