摘　　要：利用先进的大型三向六自由度地震模拟振动台进行了升船机塔柱结构抗震试验研究．试验模拟了塔柱结构基础埋深和送船渡槽与升船机塔柱结构的动力耦合作用，并充分考虑了升船机运行的特点，选取承船厢上夹紧、运行中及平衡块上锁定等３种典型工况，分别考虑地震作用．得到了升船机塔柱结构的动力特性和动力反应，为升船机塔柱结构抗震设计提供依据．The structural earthquake resistance characteristics of the ship lifter tower in Geheyan project are studied in model test on a 3 D six freedoms shaking table. The filling depth of the tower foundation and the coupling of the aqueduct with tower structure are simulated. Three typical operation conditions are considered respectively: the ship tank is clipped at the top position of the tower, the ship tank is moving in the process of lifting, the balance mass is locked at the top position. The dynamic characteristics and seismic responses of the tower structure are obtained.\
