首次建立了獨立於大型地震勘探專業軟體的開放式構造地質模型輸入系統，開發了針對于射線層狀結構模型和網格化波動方程模型的輸入軟體，大大地簡化了模型輸入的過程，極大地提高了構造地質模型的輸入效率，解決了以往模型輸入精度和效率不高的兩大難題。 -
Some stiffness matrices of special elements such as rubber bearings and components with field are derived from primary - secondary and inverse transform in structural matrix analysis. then, seismic response analytical models and non - isolated continuous rigid frame bridges are set up, while considering the interaction of soil - pile - structure and traveling wave effect simultaneously. finally, the seismic time history response of the two models is calculated by means of the finite element method, and the results show that the isolated bridge posses powerful earthquake resistance
首先論述了公路大跨徑橋梁的地震反應分析方法，其中包括樁-土-結構相互作用、行波效應等因素對結構物的影響；其次，利用結構矩陣分析中的主從變換和逆步變換，推演了幾個特殊單元的剛度矩陣，包括橡膠隔震層單元和帶剛域構件單元；最後，考慮樁-土-結構相互作用和行波效應的結合，分別建立隔震與非隔震連續剛構橋地震反應分析模型，通過有限元法對兩種結構進行時程分析，結果表明：隔震層上部結構的地震加速度反應、位移反應均明顯減小，這說明隔震的連續剛構橋具有很好的抗震能力。 -

Therefore the dynamical characteristic is acted as detected parameter for fractured detection ( primary amplitude secondary frequence ). and the amplitude of mean sguare and central frequence are acted as evaluational parameter, based on the those studies, the new ideas is put forward that fractured azimuth is dected by lateral difference and fractured density is dected by vertical difference for three facters of fracture, wavelet acted as analysis tool and direction by wave field characteristic applied the multiple scale edge dectection and self - adaptive edge detection into the detection theory of seismic fractured azimuth, also put forward the wavelet different scale filter method of the fractured azimuth detection
因而，確定了主要以振幅，其次是頻率的地震波動力學特徵作為裂縫檢測的被檢參數和均方振幅和中心頻率作為檢驗檢測結果正確與否的評價參數。在上述研究基礎上，針對裂縫的三要素，提出通過橫向求異檢測裂縫方位和縱向求異檢測裂縫密度的新思想。並以小波作為分析工具，以潛山波場特徵作指導，將數字圖像處理中的多尺度邊緣檢測和自適性邊緣檢測引用到地震裂縫方位檢測中來，並提出了小波變尺度濾波法新的裂縫方位檢測法。
