摘　　要：通过对吴洼东沟排水倒虹吸水力计算结果与模型试验结果的对比,表明所采用的水力计算方法合理,计算结果可靠。采用SAP2000和ANSYS两种方法对管身段的结构进行计算,结果表明两种方法计算结果基本相近,SAP2000计算结果略大,内力趋势基本相同。通过计算发现本工程温度对弯矩的影响幅度小于10%,吴洼东沟排水倒虹吸设计具有一定的代表性,值得类似工程参考。It is showed by comparison of hydraulic calculation and model test results of inverted siphon for drainage of Wuwadong channel of South-to-North Water Diversion Project that the applied calculation method is reasonable and the calculation results are reliable.The structure of pipe body is calculated with SAP2000 and ANSYS methods respectively,the results show that the two methods are basically similar,and the internal force trend is basically the same,only the results calculated with SAP2000 is slightly large.It is also found after calculation that the impact of temperature on bending moment is less than 10%.The design of inverted siphon is of certain representation and it can provide some reference for similar projects.
