VSP与CT技术对在役高桩码头结构损伤的检测与应用

在役高桩码头结构检测时由于结构形式复杂、需水上作业等因素,采用传统方法难以对其进行全面损伤检测。本研究在自主研发相关仪器设备的基础上,综合采用VSP基桩测试设备与混凝土结构内部损伤CT扫描设备,对船舶撞击后的某油田钻井平台码头进行检测与评判。检测结果发现,采用VSP与CT联合检测技术,能对在役高桩码头上部结构及基桩的损伤进行准确检测,并可根据检测结果对码头上部结构与基桩的损伤程度做出科学的评价,较好地解决了在役高桩码头结构损伤全面检测的技术难题,可作为一种新型的在役码头检测手段进行应用推广。

Structural damage detection of in-service high-pile wharf using VSP and CT technology

The comprehensive damage detection of in-service high-pile wharfs is difficult because the structural type is complex and water operations are needed.Based on the independent research and development equipment,we adopt the pile integrity test equipment named VSP and concrete internal damage CT equipment to carry out detection and assessment on an oil drilling platform wharf after ship collision.The results show that the upper structure and piles can be detected accurately using VSP and engineering CT,and the degree of damage of upper structure and piles can be evaluated scientifically according to the results.It can be promoted as a new detection method of in-service high-pile wharves.
