摘要

运输资产的水下工程评估历来主要依赖于传统的载人商业潜水作业,使用视觉测试(VT)和触觉检查方法来检测表面不连续性并评估现场条件。在实际应用中,由于在水下环境中进行检查所固有的多重挑战,这种方法往往是次优的。现代水下检查越来越依赖新技术,在传统的潜水检查中使用VT以外的无损检测方法,以更广泛地了解资产及其状况,提高效率,同时降低过程中的风险。如今,水下工程检查员采用传统的无损检测技术,包括VT、超声波检测(UT)和磁粉检测(MT)技术,以及声学(声纳)成像技术和遥控潜水器(ROV),以获得有关资产和邻近水道状况的更详细信息。这种方法提高了检查的安全性和效率,并降低了桥梁所有者和最终用户的风险。本文讨论了当今的水下桥梁检测方法,强调了所使用的无损检测技术及其优点。

Underwater Inspection of Highway Bridges - Recent Trends and Technologies
Underwater engineering evaluations of transportation assets have historically relied largely upon conventional, crewed commercial diving operations, using visual testing (VT) and tactile examination methods to detect surface discontinuities and evaluate site conditions. In practical application, this approach alone is often found to be suboptimal, due to multiple challenges inherent in conducting inspections in the underwater environment. Modern underwater inspections are increasingly reliant upon new technologies, and nondestructive testing methods beyond VT are used during conventional diving inspection to gain a broader picture of the asset and its condition, increasing efficiency while lowering risk in the process. Underwater engineering inspectors today employ traditional nondestructive technologies, including VT, ultrasonic testing (UT), and magnetic particle testing (MT) techniques, in concert with acoustic (sonar) imaging techniques and remotely operated vehicles (ROVs) to obtain more detailed information about the asset and adjacent waterway conditions. This approach enhances the inspection’s safety and efficiency and reduces risk to the bridge owner and end user. This article discusses today’s underwater bridge inspection approach, emphasizing the NDT technologies utilized and their benefits.
