摘要: 郭君(1983-),男,063009河北省唐山市。模型在边坡变形监测中的应用研究  郭君,甘德清,张伟航,贾静丽(河北理工大学)介绍了以往露天边坡变形监测只是对变形数据进行分析,寻求简单的、以数找数的规律,或者只是单单从岩土力学的知识来寻求变形的整体变化。露天边坡变形涉及到的因素很多,如岩石应力、节理、裂隙、地下水位、爆破冲击力等,不同地区影响变形的因素也不确定,分析了影响变形的主要因素与实测变形值组成GM(1,N)模型,探讨了GM(1,N)模型在变形应用中的可行性。

Abstract: In the monitoring of open pit slope deformation, previous deformation prediction always just analyzed on deformation data, just seek the simple law of get the data on the basis of data, or only start from knowledge of rock and soil mechanics, to seek overall change of deformation. Factors involved on deformation of open pit slope are analyzed, such as rock stress, joint, fracture, groundwater level, blasting impact force and so on, and factors which influence the deformation are relate to actual situation of region. Based on previous research, GM(1,N)model was composed by using main factors which influence deformation and measured deformation value, the feasibility of GM(1,N)model in the application of deformation is discussed.

Key words: GM(1, N)model, Slope deformation, Prediction accuracy
