熊猫苑圈舍后山崩塌危岩带稳定性分析
|
摘要
熊猫苑圈舍后山崩塌是"5.12"地震中发生的一处地质灾害,危岩带上方滞留的松散块石和潜在不稳定块体,对下方中国大熊猫保护研究中心构成严重威胁。本文根据地质勘察资料,论述了熊猫苑圈舍后山危岩带的基本特征、发生机理等,采用赤平投影方法对危岩带进行了稳定性分析,预测危岩可能的破坏方式,并针对灾害体破坏模式、危害对象等特征,提出了主、被动结合的综合防治措施,以保证下方大熊猫、饲养人员的生命财产安全。
The rockfall in panda sheds mountain was a geological disaster that occurred during "5·12" earthquake.The residual loose body and potential unstable rock mass of the mountain has posed a serious threat to China Giant Panda Protection Research Center below.According to geological survey data,this paper discusses the basic characteristics and occurrence mechanism of the unstable rock belt,uses stereographic projection method to analyze the stability of rock belt and predicts its possible failure mode.Considering the failure mode,the potential victims and other characteristics of the disaster,the paper makes active and passive control measures in combination so as to ensure the safety of pandas and breeders below.
