高桩码头维护技术评价指标与体系研究

性能退化问题是影响高桩码头使用寿命的重要因素。运营过程中的船舶撞击、岸坡变形等因素也会对结构构件造成损伤。高桩码头维护技术多种多样,但对于损伤后码头的修复与维护,目前尚无科学合理的选择方案。针对高桩码头维护技术的特点,提出常用维护技术的专项指标和评价指标,建立可实现不同维护技术在同一层次进行评价指标对比的评价体系,为高桩码头维护技术的选择和维护设计方案的制定提供指导。

Evaluation index and system of maintenance technology for high-pile wharf

The performance degradation is an important factor affecting the service life of high-pile wharf.Other factors,such as ship impact and bank deformat,may cause damage to structures or members during the operation process.To repair and maintain the damaged wharf,there is no scientific and reasonable choosing method in many kinds of maintenance technologies for the high-pile wharf.According to the characteristics of the maintenance technology for the high-pile wharf,we propose special index and evaluation index and establish the evaluation system to compare evaluation indices of deferent maintenance technologies at the same level,and to provide a guidance for the maintenance technology selection and maintenance design method of high-pile wharf structures.
