Analytic Hierarchy Process for Importance Extraction of Pile Cluster Foundation Components
摘要
Abstract
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.关键词
