Research On The Structure Styles Of The Arched Bridge Foundation Of The Track Of The Cable Machine

In the project of the power station constructs, we usually need the vertical transportation system of the cable machine to transport the reinforcing bar of concrete or other materials into the storage., the cable machine can be the translation type or the radiation type to move. The track foundation of the cable machine generally lies in two banks of the slope or the platform on the hillside river valleys on the ground, both sides of the river valley often develop ditches which are vertical to the valley. Building the track foundation of the cable machine in the ditch, we usually use the gravity type structure or array structure, but the project amount is great, and construct time is long, can we use more light arched bridge structure pattern as the foundation of the track of the cable machine?Generally, the arched bridge is a structure which mainly bear the vertical loads, but even the routine railways , highway arched bridges, bear certain level loads too, for example: The wind loads, water loads (especially overflows bridge). From apparent, it seems that the level loads on the arched bridge which is used as the track foundation of the cable machine are greater than the vertical loads. But if we make a comparison between the live level loads on the cable machine and the deadweights of the arched bridge(permanent loads),we can find that the former is far more greater than the latter, and as the arch span increasing, their ratio becomes smaller. For example: the ratio of the arched bridge whose arch span is 45m is about 15%~20%, but when the span is 100m it becomes more smaller, less than 5% of the deadweights of the arched bridge. We can utilize the torque caused by partial deadweight to offset the torque caused by the most of the level force, thus we can make it possible that the arched bridge can be the foundation of the track of the cable machine.In this paper , FEM is used to discuss the feasibility of the arched bridge as the foundation of the track of the cable machine and the ANSYS is used to analysis the static force and the dynamic force of the arched bridge structure in different work conditions. The feasibility of the structure is also be proved. Through the comparison between the stress and the strain of the varied section and constant section of the arched bridge in different work conditions, and through the optimizing the restrain conditions of the structure, the strength condition of the arched bridge is improved, and arched bridge structure as the foundation of the track of the cable machine is used more widely. Through the analysis of the static force and the dynamic force of the arched bridge in different work conditions by using the methods of the shelly unit and three-dimensional entity's unit analysis, the reliability of the results can be proved.
