Static And Dynamic Analysis On Sluice And Optimum Design Of Upper Frame

For several decades, the construction of water power in our country has developed greatly. Sluice is not only used to block, but also flush water. So it has the features of blocking and flushing structures. Sluice pier and upper frame are the important parts in the sluice constructer. It is necessary to analyze and design on the structures.Traditionally, the simplified quasi-static method is adopted to study the stress and strain induced by earthquake for sluice. This method is infeasible for the sluice built on the dam body, and is proper simplified on the calculation of the engineering. However, this method can not take into consideration the effect of uneven settlement of the ground on its upper structure. A more satisfactory method— three-dimensional finite element is used to study by a model that can represent both the dynamic properties of ground and the upper structure in the paper. And on the basis of static and dynamic analysis, optimization on the upper frame is carried out.This paper is mainly studied three-dimensional finite element on sluice construction, and established the entire model including sluice pier, ground, the floor board, and the upper frame as a whole body. Through analysing the static and dynamic problems, we can draw the reasonable conclusions. Additional, this paper is also made researches on acceleration response spectrum to solve the dynamic problems of sluice construction. And quasi-static method is used to calculate the effects of seismic shock on the upper frame.This paper is mainly used the ANSYS software to analyse the static and dynamic response on a sluice project of power station by the three-dimensional finite element. The whole model is employed elastic and ideal elastic-plastic material to simulate. On dynamic analysis, modal analysis and acceleration response spectrum are used. By analyzing and calculating the deformation and stress distribution status of foundation under time of completion, operating period and earthquake condition, and the structure self-oscillation character and dynamic response under the degree horizontal seismic were gained beside. Then the security and rationality of the whole structure were comprehensively evaluated.Additionally, this paper is adopted ANSYS software to optimize the upper frame, and obtained more feasible cross size.
