基于关联度的滑坡位移特征分析

Analysis landslide displacement characteristics based on correlation degree

关联度矩阵既是决策的原始依据,又是系统优势分析的基础。在变形观测数列分析中,它的一个重要作用就是选择变形模型的最佳因子子集合。根据空间关联度矩阵内各元素的大小及变化规律对滑坡空间受力特点及变形性质进行分析,通过关联度来分析判断该滑坡各监测点所处区域的同步性发展过程,进一步丰富滑坡变形破坏机制研究的手段,对滑坡治理以及预测预报则具有重要的理论和实际意义。本文通过东拉滑坡的地表位移监测数据进行整理分析,建立关联度模型并计算出该滑坡地表位移监测点的关联度,根据关联度分析说明该滑坡的中后部同步性较强,力学联系较紧密,是滑坡下滑动力来源;滑坡前缘同步性较差,力学联系较差,也是该滑坡失稳的最关键区域,从而进一步加深了对该滑坡变形破坏机制分析和发展趋势的认识。

Correlation matrix based on both the original decision,and is the basis of system benefits analysis. The number of columns in the deformation observation analysis,it is an important factor role is to select the best subset deformable model. Depending on the size and the variation of the elements of the space correlation matrix of landslide spatial mechanical properties and deformation characteristics of the analysis,you can analyze and judge the synchronization of the development process of the landslide monitoring points at the area according to relevancy,thus enriching the landslide deformation Failure of the mechanism means,which has targeted forecast of Landslide and have important theoretical and practical significance. In this paper,the East pulled by landslides surface displacement monitoring data consolidation analysis,correlation of the model and calculate the degree of association of the landslide surface displacement monitoring points,based on correlation analysis shows that the decline in the rear of the synchronization is strong,compared Mechanics close,falling power source landslide; landslide synchronization is poor,poor mechanical contact,also is the most critical area of the landslide,thus further deepening of the landslide deformation and failure mechanism analysis and understanding trends.
