摘　　要：构件重要性的提取是群桩基础损伤识别控制性预测模型的首要问题,由于群桩基础在服役期间,受到外界因素影响复杂,且各因素间存在叠加和相互影响。基于广义结构刚度理论,以高桩码头为代表性结构,计算量船舶撞击力、系缆力、堆货荷载、门机荷载作用下构件重要性系数。将层次分析法引入群桩基础构件重要性影响因素的提取中,构建由构件重要性、构件属性、构件影响因素分别作为目标层、准则层、指标层的分析模型;计算各类荷载作用下码头构件重要性系数的权重,并根据权重进行构件重要性系数的组合。通过合理的构建编号和数据表格整理,并引入了构建重要性系数色块表达方式,更加直观明晰的对比分析了不同荷载对码头各类构建的影响,对比了组合荷载与单一荷载的差异。明确了群桩基础存在水平向和竖向荷载两条传递路径,分别位于中前上部排架和两侧的排架。The extraction of the importance of components is the primary problem of the identification and prediction model for pile cluster foundation damage.Pile cluster foundation in the service period is affected by the complicated external factors,which show the superposition and interaction.Based on the generalized structure stiffness theory,the piled wharf was selected as the typical structure to calculate the importance coefficients of the components under the ship impact force,mooring force,stock pile load and gantry load.Analytic hierarchy process(AHP)was integrated into the extraction of importance factors of pile cluster foundation components,and an analysis model was built by defining the importance,properties and influence factors of components as the target level,criterion level and index level respectively.By calculating the weights of the importance coefficients of the wharf components under various loads,the combination of importance coefficients of components could be made accordingly.Based on the appropriate serial numbers and data tables,the color block expression method was used for the construction of importance factors,more intuitive and clear comparison and analysis of the influences under different loads as well as the difference between the combined loads and single load.The results showed that pile cluster foundation was affected by both horizontal load and vertical load,which existed in the middle front upper bents and the frame bents on both sides respectively.
