在役码头结构检测评估现状与展望

Present situation and prospect of detection and evaluation for structure of in-service wharfs

自20世纪70年代以来,我国开始逐渐重视对码头结构的检测和评估,科学、合理地检测和评估在役码头结构的安全性、使用性和耐久性已成为迫切需要。文章详细分析和阐述了码头结构检测与评估的研究现状,并指出了目前存在的主要问题,认为合理、有效的检测技术仍需不断探索,检测信息往往有限、随机、间断且无动态反馈,评估方法经验色彩浓重。最终认为,采用荷载试验法、加强检测数据收集和积累、建立基于BIM+大数据分析的检测评估系统是提高检测评估准确性和可信性的有效途径。

The detection and evaluation for structure of in-service wharfs had beginning to get more and more attention since the 1970s in China,so scientifically and reasonably detect and evaluate the safety,usability and durability of in-service wharf structures which has been an urgent and practical need.In this paper,the present research situation of detection and evaluation of wharf structure has been analyzed and elaborated,and the main problems existing at present were point out.It is considered that reasonable and effective detection technology needs continuous development,detection information is often limited,random,discontinuous and without dynamic feedback,and evaluating methods are rich in experience.Finally,it is concluded that it is an effective way to improve the accuracy and reliability of detection and evaluation bu using load test method,strengthening the collection and accumulation of detection data,and establishing a detection and evaluation system based on BIM&big data analysis.
