孤石赋存形态的分类及稳定性分析

CLASSIFICATION OF OCCURRENCE FORM OF SPHERIC WEATHERED GRANITE AND STABILITY ANALYSIS

边坡上临近道路、居住区稳定性差的孤石极易形成落石,严重威胁人们的生命财产安全,而花岗岩孤石在自然界中的赋存形态直接影响孤石的稳定性。对自然界不同赋存形式的孤石进行分类,根据不同赋存形态的孤石特点建立力学计算模型,进行稳定性分析,为孤石的危险性评估与治理提供理论依据。

The spheric weathered granite on the slope near the road and residential area is very easy to form rockfall,Speciation of spheric weathered granite in nature directly affects the stability of boulder.Classification of spheric weathered granite in different forms of nature in nature,basing on the spheric weathered granite characteristics of different occurrence forms,the mechanics calculation model is set up,and the stability analysis is carried out to provide the theoretical basis for the risk assessment and control of the spheric weathered granite.
