摘　　要：目前对于大型钢筋混凝土结构的动力分析研究中,结构动力模型试验与破坏试验仍然是了解结构非线形动力响应与地震破坏形态的一种重要手段。原型结构与模型结构之间各种力学和物理量的相似关系至关重要。本文结合三峡升船机抗震试验,首先介绍了原型基本概况,基于原型对模型进行了设计,给出相似性关系。根据需要研究的内容,给出了可实施的具体方案,包括准备阶段、弹性小震阶段、设计地震阶段和超设计地震阶段,并对加载的地震时程进行了设计。期望研究成果对今后开展大型钢筋混凝土结构的破坏试验工作有一定的指导和借鉴作用。For the analysis of Large-scale reinforced concrete structures,the structural dynamic model tests and failure tests are important tool to obtain non-linear dynamic response and failure modes of the earthquake.A variety of mechanical and physical relationship between the prototype and model is essential.First,the basic profile of Three Gorges Project ship lift is introduced.The model based on the prototype is design and given the similarity relations.Study of the content as needed,can be implemented given the specific program,such as preparation stage,small earthquake stage,design earthquake phase and beyond design stage,and earthquake loading schedule is designed.Results is hoped to give some guidance and reference for failure test of resemble large-scale reinforced concrete structures.
