断层及邻区视错动变形系统分析模型

基于跨断层及邻区地壳形变资料，结合板内断层震间、同震错动变形活动、多断层错动变形活动实际，构建从单一断层震间整体视错动变形分析模型、沿断层视错动变形空间分布分析模型、同震视错动变形整体与空间分布分析模型，到多条平行断层视错动变形整体分析和沿断层视错动变形空间分布分析等系统性分析模型。实例表明，该系统分析模型可从不同角度全面揭示震间断层及邻区视错动变形活动的整体与细部特征、变形活动状态或阶段、多断层系统彼此间的关联性活动以及同震及震后调整视错动变形等。

Systematic Analysis Models of Visual Slip Deformation on Faults and Their Surrounding Area

Systematic analysis models were developed and set up according to actual phenomena, including inter-seismic and co-seismic dislocation deformation of fault, single fault and parallel fault system action in inter-plate, fault activity, and seismic risk analysis, etc. Actual examples show that fault action parameters and their changes in the area or along faults can be obtained by the models using crustal deformation data, including various kinds of information on co-seismic displacement and de-locking depth of Longmenshan fault zone, harmonizing action between Longmenshan and Longriba fault zone after the Wenchuan MS8.0 earthquake, spatial distribution of deformation gradient in Zhangjiakou-Bohai tectonic zone and its adjacent region, locking degree distribution along the tectonic zone, etc. Not only is the availability of the models proven, but research on the tectonic action of the fault system and its surrounding area can be enriched by the models.
