非坝体水工建筑物结构抗震模型试验研究

Model Test Research on Structural Earthquake-resistance of Non-dam Hydralic Structure

针对非坝体水工建筑物结构特殊、振动性态复杂、地震反应特性和抗震问题与坝体建筑物不同,基于非坝体水工建筑物模型试验的基本原理,对动态模型实验时考虑模型与原型的相似关系、模型材料选择、边界模拟、地震动输入等一系列问题从模型试验关注的问题和重点进行了评述,为实验提供了相应的理论依据。

Non-dam hydralie structures often include underground structure, hydralic tunnel, aqueduct bridge, floodgate,ship lift tower, intake tower, hydralic frame construction, etc. There are different from dam. Non-dam hydralic structures are special and hold more complex vibrating character, the matter of earthquake response and earthquake-resistance are different from dam. How to consider the similarity between model and antetype, the choice of model material, the imitating of boundrary, the importing of earthquake motion and many other problems in non-dam hydralic structures are needed to be researched during model test. This article discusses many problems and focal points that must be paid attention to in the case of carrying out model test, and the basic rules as well as requirements of non-dam hydralie structures are also worked over in order to provide theory for model test.
