Aiming at the pivotal project is decorated jointly by sluice and pumping station, thus the relationship between each other is more complex. By using 3-D finite element software ABAQUS, the structure of pumping station was studied. Two methods were used when modeling and analyzing. For the method 1, only the model of pumping station was built and the check sluice was taken as a side load when calculating. For the method 2, the whole model of the joint hub of sluice and pumping station was built. The displacements and strength of the structure of pumping station can meet the requirements according to the calculated results. There is little difference between the calculated results of the two kinds of methods by comparison, but for the method 1, the calculations about displacements are all unsafe and it should be given enough attention, thereby the reliability and security of the design of similar projects will be guaranteed.
