Research Of Sluice Overall Structure Design's Method And Application Of Empty Box Type Soil Baffle

Considering floor, pillar and groundwork as a whole frame, a open sluice finite element model was established and the result was believable. This kind of model not only could availably consider the interaction between floor, pillar and groundwork, but also could expediently handle various complicated conditions of geometry, physics and load.In the thesis, a open sluice overall finite element structural calculating model considering floor and pillar and working-bridge and groundwork as a whole frame was established. Compared the result with open sluice overall finite element structural calculating model which the working-bridge has not considered. The conclusion: considering the influence of working-bridge, the distributing of internal force in the floor can be improved and the transverse intensity of sluice can be increased availably.Considering the limbic pillar received bigger earth pressure, when the limbic pillar linked with two banks directly, because the discrepancy between the load of limbic pillar and the load of groundwork was great, it would beget not symmetrical sedimentation and bigger internal force in the floor, affect turning on and turning off of strobe and even engender crack. At this time, empty box type soil baffle was applied. A open sluice overall finite element structural calculating model considering empty box type soil baffle was established. Compared the result with open sluice overall finite element structural calculating model which empty box type soil baffle has not considered. The conclusion: applying empty box type soil baffle would minish the internal force in the floor and the limbic pillar and not symmetrical sedimentation.
