港口码头健康检测与评估技术研究现状及主要问题

港口码头由于常年服役于复杂的自然环境下极易出现破损,这些破损和损伤势必会影响码头的健康状况,对港口的安全运行造成一定隐患,研究港口码头健康检测与评估技术显得非常必要.鉴于此,本文对国内外港口码头在健康检测与评估方法两方面的研究和主要问题进行了综述和分析.目前港口码头主要采用单一的检测方式、评估方法,并不能对码头的健康状况提供合理、客观的评估结论;基础完整性检测,无论在理论方面还是在应用方面,都远未达到成熟可靠的程度;在评估指标体系的构建方面还有待进一步的研究,以实现混凝土结构耐久性评估工作由定性向定量的转变、由局部向整体的转变、由单因素研究为主向多因素、荷载与环境耦合作用研究的转变.

Overviewof current situation and main problemsof health inspection and assessment technology for ports

Ports are prone toappearbreakage and damage for their service in complex natural environment. The damage is bound to affect thehealth of whole structure, and cause some hidden trouble to the safe operation of the port. thus, it is necessary to study the health monitoring and assessment technology for ports.In view of this, this paper summarizes and analyzes the two aspects of health inspection and assessment methods for port terminals at home and abroad.Currently, reasonable and objective evaluation conclusions for the port health status could not be provided, for the detection mode and single evaluation method are the mainmethods.The basic integrity test, either in theory or in the application, are far from mature and reliable degree. Further research in the construction of evaluation index system should be conducted for the concrete structure durability evaluation,which will transform research from qualitative to quantitative, from thelocality to the overall, from single factor to the multi factor, andload and environment interaction are also included.
