摘　　要：渡槽结构由于上部水体及槽体重量大,地震时动力反应强烈。按传统抗震设计难以保障其安全性,采用减隔震装置是解决渡槽抗震安全的可行措施,适度延长隔震结构周期与调整阻尼是控制渡槽振动的有效途径。由于无渡槽减隔震设计规范,故借鉴桥梁减隔震设计原理,结合某渡槽进行了减隔震参数设计,并结合工程实例给出了设计步骤。Since the weight of the aqueduct together with its inside water is very heavy, the dynamic response of the structure is intensive under the seism action. The structural safety couldn＇t be guaranteed according to the traditional antiseismic design method, therefore, to make use of the seism isolator is a feasible measure to ensure the safety of the aqueduct-bridge, and to prolong the period and adjust the damp of the aqueduct-bridge is an effective approach to control the vibration of the aqueduct. Due to no design criterion about the aqueduct-bridge to be followed currently, so the isolation principle of the bridge is used for reference and applied to the parameter design of a aqueduct-bridge, and the design process is given at the same time.
