摘要
应用瑞典MALA地质雷达对天津市汉沽区海挡外移工程的海堤防浪墙混凝土与其下部基础之间是否脱空及脱空区范围进行了检测,经现场调查确认脱空位置并复核检测结果,发现海堤防浪墙路面下存在不同程度的脱空及空洞,能给海堤的维修提供可靠依据。
In this paper,the Swedish MALA geological radar was used to detect the se a wall dike roof of the sea wall shifting project in hangu district,tianjin. As is known to all,highlighting the advantages of the geological radar on NDT,use the technical advantages of seawall parapet wall between concrete and its lower base pavement and pavement zone were tested and confirmed by the field investigation road.
