摘要
震后桥梁结构震害快速评估能够为地震应急救援提供重要参考信息,对减灾工作具有重要价值。为了快速准确地评估遭受地震影响梁式桥的破坏状态,使梁式桥震害评估方法在地震应急中发挥更大作用,基于统计回归模型、神经网络模型和推断模型等三种梁式桥震害评估模型,采用VC++6.0及Access2003数据库软件开发了有关评估软件,并以桥梁震害资料为算例验证了软件的可靠性。
Immediate seismic damage assessment of bridge usually provides important information for emergency rescue that has great value to disaster reduction.In order to quickly and accurately evaluate the damage state of beam bridges,which are suffered from intense earthquake,and efficiently apply damage assessment method of beam bridges to earthquake emergency response,a evaluation program,which is based on statistical regression model,neural network model and inference model,is built with VC＋ ＋6.0 and Access2003.The reliability of the software is validated by damage information of bridges in Wenchuan earthquake.
