地表质量重新分布是引起地壳形变呈现季节性变化的主要因素，能够利用GNSS技术对其进行有效的监测，还可以通过表面负载模型来拟合。现有研究表明由GNSS和负载模型获得的季节性地表形变存在明显的差异，尤其是水平方向。本文通过比较全球900个测站IGS第二次重处理与负载模型生成的三维季节性变形，结果表明负载形变可以解释43%的GNSS垂直周年变形，水平方向可解释率低于20%。为了分析剩余GNSS季节性形变的可能来源，本文定量研...

地震是威胁人类生存安全最大的自然灾害，被称为群灾之首。快速精确测定大震破裂区域是震后快速响应、科学指导救援的基础。传统方法主要依赖强震观测网络数据，然而强震近场观测数据易受仪器基准倾斜、旋转影响，导致难以获得准确的地震波形，进而影响大震破裂范围反演的准确性。课题组基于高频GNSS观测网实时测定的大震同震波形，提出了一种基于线源模型的大震破裂特征快速确定方法，该方法采用经验尺度关系、方向性衰减回归...
