The Study On The Numerical Simulation For Vibration Compacting Of Concrete In Large-scale Diversion Channel

South-to-north water diversion project is the large-scale interbasin water transfer project. the construction quality of the channel lining project is very important to the safty and durability of the project. so, based on the construction of the south-to-north water diversion project, through the investigation at aboard and the study at home and the serious conclusion of the advanced technique at home and aboard, This thesis carries on an investigation into the theory of vibro-compacted concrete. this theory is applicable to large-scale mechanized construction of the channel, and the benefit of the theory is very significant to our society and economy. the effect that the parametes of the concrete molding equipment has on the quality of the concrete is definited. So it can provide a good theoretical foundation for us to realize the large-scale mechanized lining construction of the channel.As a modern research methods of the structural dynamic characteristic, Modal analysis is gradually becaming the core of the dynamic analysis and design. The natual frequency and the mode shape of the structure what it determines can let us predict the vibrating reaction in response to the vibrating load in and out the struction,and is is the important parameters of the structural design. So it becomes the original beginning of some other dynamic analysis. For example, the transient dynamic analysis. In this thesis, using the computer software (ansys), modal analysis of the vibro-compacted concrete is accomplished.it is prepared for the transient dynamic analysis.In this thesis, the computer software (ansys) is used to complete the transient analysis of the vibro-compacting concrete. Ansys is used to simulate the vibrated influence of the vibro-compacted concrete under different amplitudes, different frequencies, different distances and different obliquities. the approximate relationship between vibrating parametes and vibro-compacted effect is obtained. so it can provide theoretical basis for the parameter optimization and definite of the large-scale mechanized lining equipment of the channel in the south-to-north water diversion project.
