【摘要】 根据南水北调工程钢筋混凝土多纵梁渡槽结构受力性能大比例尺仿真模型试验的需要，结合三维有限元分析结果，研制了一套符合渡槽受力特点且便于实施的加载系统，其成功经验对类似结构试验加载方案的确定具有重要的参考价值．更多还原

【Abstract】 With the need of the large scale simulation model test of reinforced concrete aqueduct bridge with multi-longitudinal beams to be used in Transmitting South-water-to-north Engineering , a loading system is studied which in conforming with the loading characteristics of the aqueduct bridge and simple for practical operation.This work settles a good foundation of the successful model test,and shows important reference for the similar structure experiment.更多还原
