研究方向 地震学的基本理论与计算方法及其在地球内部结构成像、防震减灾工作及资源勘探领域的应用。 复杂地球介质中地震波传播及结构成像 震源破裂动力学及地震物理学 震源破裂过程的成像反演 近场强地面震动定量模拟及震害预测
学术成就 1.提出了计算地震波在不规则(二维)层状地球介质中的激发与传播问题的系统的方法;该方法突破了基于瑞利假设的Aki-Larner方法对界面弯曲幅度的限制,也适用于界面弯曲幅度较大的问题。 2.系统地研究了横向非均匀地球介质中勒夫波(Love面波)的激发与传播的理论问题,提出了存在于横向非均匀地球介质中的变形振型及频散曲面的概念,并在此基础上建立了完整、精确地描述横向非均匀地球介质中地震面波的激发与传播的理论公式。 3. 提出了一种系统简洁、高效而精确的计算平行层状地球介质中面波频散及简正振型的理论方法,从根本上彻底解决了经典Haskell矩阵算法中的高频精度丢失问题。 4. 改进与完善了经典的计算平行层状介质中理论地震图的算法理论。
