摘要
采用冲击回波法对京珠高速公路某桥面上出现的开口裂纹用飞行时间法进行了检测 ,通过信号分析和后处理 ,确定了每一点的开口裂纹的深度 ,分析结果与设计和施工单位理论估算的结果相吻合 ,表明该测量方法已能适用于现场检测 。
Tests are made by impact echo method on surface opening cracks on a bridge of Jingzhu highway. By signal processing, the depths of each points on the crack are acquired. The analyzing results is the same as what the engineers estimated. It is indicates that this method prores to be functioning at on the spot measurement. Wide application prospects will be acquired.
