|
摘要
如何获取构造形变微地貌所蕴含的定量参数,对于研究活动断裂、地震地表破裂带特征来说是至关重要的。甘孜—玉树断裂是广义鲜水河断裂带向北西延伸的羽列孳生断裂,具有新活动性。活动断裂新构造活动微地貌响应是研究构造形变微地貌的最佳对象之一。近年来,一些高精度仪器已经广泛应用于构造形变微地貌的测量中。天宝VX空间测距仪是一款集成了先进的光学测量技术、量测成像技术和3D扫描技术并能捕捉扫描数据、成像数据和测量数据,并把这些数据融合一体可执行所有任务的测量仪器。本文结合甘孜—玉树断裂邓柯段的构造形变微地貌特征,系统介绍天宝VX空间测距仪获取该段活动断裂的定量化形变参数,这些参数对我们深入了解甘孜—玉树断裂邓柯段活动性质有着重要的意义,并对天宝VX空间测距仪在构造形变微地貌测量中的应用提供了重要的参考资料。
Tectonic micro geomorphology behind the quantitative parameters is the key to study active faults and the surface rupture etc. Broadly speaking,the Ganzi-Yushu fault zone is feather fracture which extends northwestward Xianshuihe fault and is also an active fault. The Features of the active fault zone is one of the best subjects for study tectonic deformation of micro geomorphology in the neo-tectonic active micro geomorphology. In recent years,a number of high-precision instruments have been used in the measurement of micro geomorphology. The Trimble VX Spatial Station Specifications is an integrated of advanced optical measurement instrument,which use the imaging techniques and 3D scanning technology. It can capture the scan data,imaging data and the measured data and store these integrating data. This instrument can perform all the tasks. In this paper,we collect the Ganzi-Yushu fault,Dengke section tectonic deformation micro geomorphic features,and describes how to obtain quantitative de-formation parameter of the segments of active faults by using Trimble VX Spatial Station Specifications. These pa-rameters to our in-depth understanding of Ganzi-Yushu fault Dengke section activity properties have important meaning,and Trimble VX Spatial Station Specifications in tectonic deformation micro-topography measurement application provides the important reference.
