工作
從事地震波傳播理論及震源理論研究。提出了計算地震波在不規(guī)則(二維)層狀地球介質(zhì)中的激發(fā)與傳播問題的系統(tǒng)的方法;由于該方法突破了基于瑞利假設(shè)的 Aki-Larner方法對界面彎曲幅度的限制,也適用于界面彎曲幅度較大的問題。系統(tǒng)地研究了橫向非均勻地球介質(zhì)中勒夫波(Love面波)的激發(fā)與傳播的理論問題,提出了存在于橫向非均勻地球介質(zhì)中的變形振型及頻散曲面的概念,并在此基礎(chǔ)上建立了完整、精確地描述橫向非均勻地球介質(zhì)中地震面波的激發(fā)與傳播的理論公式。提出了一種系統(tǒng)簡潔、高效而精確的計算平行層狀地球介質(zhì)中面波頻散及簡正振型的理論方法,從根本上徹底解決了經(jīng)典Haskell矩陣算法中的高頻精度丟失問題。改進與完善了經(jīng)典的計算平行層狀介質(zhì)中理論地震圖的算法理論。近年承擔(dān)了科技部、教育部、國家自然科學(xué)基金委員會各類科研項目多項。發(fā)表學(xué)術(shù)論文被SCI、 EI收錄30余篇。
1996年獲國家杰出青年基金資助。
