变形曲线的SVM分类及在变形等级划分中的应用

Deformation curves classification by SVM and its application in grading of deformation

变形等级的划分对信息化施工和及时采取相应针对性防治措施以及地震形变在线式分析和预警系统的研究中具有重要的理论与实践意义。本文提出以曲线的曲率和二阶导数来描述变形曲线的特征,并作为SVM输入量对变形进行自动多类分类。

The division of deformation level is of practical and theoretical significance to the construction of information, taking targeted control measures appropriately and timely and the research of earthquake deformation online analysis and warning system. A way trying to describe the characteristics of the deformation curve with its curvature and second derivative was introduced in this paper, which were also set as the input parameters of automatic SVM multi-category classification.
