摘　　要：漳河渡槽是南水北调中线工程主要跨河建筑物之一,为确保工程的安全和结构的优化设计,特进行1∶6的钢筋混凝土仿真模型试验。对钢筋混凝土渡槽结构仿真模型试验中材料性能、模型的设计制作、结构自重的模拟及水荷载施加方法等关键技术进行了分析讨论。重点阐述试验过程中结构和加载方式的模拟。给出在4种工况下渡槽关键部位的应变和变形,并作了比较,为渡槽提供了需要改进的结构设计建议。Zhanghe river aqueduct is one of the main river?crossing constructions in the Middle Route of Water Transfer Project from South to North. For the safety of the project and optimization of the design, reinforced concrete emulation model experiments were done with a scale of 1∶6. Some key technologies are analyzed and discussed including the material performances, model design and construction, simulation of deadweight and water loading method. The simulations of construction and loading mode are expounded in focus. The strains and distortions of four cases are given and compared and some improvement suggestions are also put forward.
