生态复合墙结构在土-桩-结构相互作用下隔震设计研究分析

Isolation design analysis of soil-pile-eco-composite walls interaction system

利用时程分析法对天然地基上带群桩基础的生态复合墙结构进行隔震设计研究分析。建立弹簧单元模拟群桩基础,采用Davies方法确定桩的刚度;利用SAP2000建立生态复合板隔震模型。用时程分析法进行地震反应分析,比较隔震结构和非隔震结构时程反应分析结果,并找到其中规律,为隔震设计提供设计依据。

Time-history method was adopted to perform Isolation Design analysis for eco-composite wall structure with grouped pile foundation resting on natural foundation soiL The substructure technique was adopted to simulate pile group with a group of springs,the grouped pile stiffness was determined with Davies method. Using SAP2000 establish an eco-composite wall isolation model. This paper uses time-history method to analysis earthquake response and compares the results of time-response analysis of the isolated structure with non-isolated structure＇s;contrast the effect of isolation of different damping ratio and find the rules to provide the basis for isolation＇s design.
