摘要
为了进一步拓展分形理论在土木工程中的应用,首先回顾了分形理论的发展历程、基本概念、基本原理及分形维数;然后就其在国内外的土木工程材料、岩土工程、地震工程、结构损伤检测领域中的应用现状进行了总结和述评,并对分形理论与神经网络及数据融合相结合用于钢管混凝土拱桥的损伤识别研究进展进行了介绍;最后对今后的发展前景进行了展望。研究表明:分形理论在土木工程特别是将它与其他技术融合进行损伤检测是切实可行的、有效的。
In this paper, in order to expand the application of fractal theory, the history, concepts, principles of fractal theory are reviewed firstly; then a summary and overview are given to the application of fractal theory in civil engineering materials, geotechnical engineering, earthquake engineering and structural damage detection throughout the world; and the study on fractal theory integrating with neural network and data fusion applied to damage identification is introduced. The prospect and trend are forecasted fmally. The study shows that the application of fractal theory in civil engineering, especially the fractal theory integrating with other techniques applied to damage detection for a concrete-filled steel tubular arch bridge, is feasible and efficient.
