工作
从事地震波传播理论及震源理论研究。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;由于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。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。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。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。近年承担了科技部、教育部、国家自然科学基金委员会各类科研项目多项。发表学术论文被SCI、 EI收录30余篇。
1996年获国家杰出青年基金资助。
