摘要

二里崩塌为"5.12"特大地震所诱发的次生地质灾害,发育有4个崩塌灾害点,需采取可靠的防治措施。通过对二里崩塌的地质环境条件、崩塌基本特征的调查分析,结合工程地质分析方法,指出二里崩塌主要是倾倒式崩塌和滑移式崩塌两种类型。对两种不同成因类型的崩塌进行了较为详细的论述,研究了两种类型崩塌的形成机理,并据此提出了针对崩塌落石的防治工程措施。
The Erli collapse is a secondary geological disaster induced by the 5.12 Wenchuan earthquake,where 4 collapse spots are developed and reliable engineering measures need to be adopted.Through investigation and analysis of the geological and environmental conditions and basic characteristics of collapse,combining with method of engineering geology,the two disaster types of Erli collapse are identified,namely inclined collapse and slide collapse.We studied the two types of collapse with different forming mechanisms in detail and proposed the engineering prevention measures for collapse and rock-fall.
