基于粒子滤波的唐山台跨断层数据分析

Analysis of Tangshan Cross-Fault Deformation Using Particle Filter

基于游丽兰等给出的跨断层单测线动态系统模型,采用残差重采样粒子滤波算法对唐山台跨断层水准(基线)观测数据和降水量、气温等辅助观测数据进行综合处理。假设跨断层形变观测量仅受辅助观测项的影响,可以根据残差重采样粒子滤波结果获得环境因子(降水量、气温)对唐山台跨断层形变观测量的影响和断层运动情况。

Based on the dynamic system model of across faults deduced by YOU Li-lan,using particle filter based on residual resampling method, we analyze the cross-fault leveling data of Tangshan station combing with auxiliary observations such as temperature, precipitation and so on. Assuming that the deformation observations are influenced only by these observed environmental factors （such as precipitation and the temperature） , the influence quantity of these environmental factors and the fault activity can be obtained.
