摘要
基于桥梁结构的动力特性,结合人工神经网络,探讨了分步进行探伤、定位和量估的桥梁损伤诊断方法,以襄荆高速公路某一简支梁桥为算例,采用ANSYS程序建立了三维有限元模型进行模拟损伤分析,验证了所述方法的可行性。
Based on the dynamic characteristics of bridge structures,the paper combining with the artificial neural network,explores the damage diagnosis methods of the fractional steps to explores the damage,to locate and to evaluate,adopts ANSYS procedure to establish the three-dimension element model to undertaking the damage analysis by taking some simple support bridge of Xiangfan-Jingzhou expressway,and proves the feasibility of the mentioned methods.
