某海港工程结构变形观测的数据处理和变形分析

某海港码头的钢引桥受外轮碰撞,钢桁梁结构受到严重损伤,为精确描述和确定该引桥的操作程度和变形情况,为经济赔偿和工程修复提供可靠的技术数据,需进行高精度的工程测量和严密的变形分析,本文较详细地讨论了该工程的变形观测及其数据处理与变形分析,包括用极差法和数据探测法进行观测值的质量检验和粗差剔除,采用试验修正法确定不同类型观测值的权以及钢桁架梁的局部和整体变形分析等,上述成果已作为重要技术资料用该工程的

ANALYSIS OF MONITORING DEFORMATIONS ANDDATA PROCESSING FOR A HARBOURENGINEERING CONSTRUCTION

:A steel truss bridge approach near a wharf was crashed seriously by a fo-reign ship. In order to evaluate the degree of the damages and to provide a set ofreliable technical data for repairing the bridge and for the damagereparation,precise engineering surveying methods for monitoring the deformations have beenpresented in this paper. Several data snooping approaches, such as the extremedifference method, used for quality examination and for gross error detection andidentification in data processing have also been discussed in detail. Finally a so-called "modified weights", method is introduced to gain an ideal balance of theweights between side and direction observations in the control network used formonitoring deformations.
