Analysis Of Seismic Response For High Pillar Bridge In Ultra-Deep Water

To overcome the wider surface, bridge construction project in the development towards a greater span, it also appears more and more deep-water bridge. Deep water on the theory of bridge design and construction techniques are some special problems. The earthquake in China is a multi-national, Under seismic action, Piers in deep water occurs in a certain vibration and deformation,And cause sloshing around the water body, You Yi hydrodynamic pressure of water in the form of reaction on the bridges, to change the vibration of the bridge piers, arid deformation, With this kind of action and reaction process has ground motions.In this case, this article ditch riding mule for the engineering background of the bridge pier in deep water continuous rigid frame bridge seismic performance, and the following done some analysis and discussion:(1) A lot of reading materials on the basis of summing. up the existing method of calculating the hydrodynamic pressure and its influencing factors, and details of the Morison equation calculation.(2) The ditch riding mule for the calculation model of the bridge, Morison equation method for seismic response analysis of deep water pier. In the earthquake, because of the impact of hydrodynamic pressure, pier pier top displacement of pier and pier at the end of the internal forces of water and water of the case, the obtained results were quite different.(3) To explore the depth of the seismic response of bridge piers. With the increase of water depth, the impact is also larger. Computing different hydrodynamic pressure of different degrees.(4) Application deep seismic response analysis of semi-analytic method, on the deep hollow pier rigid frame bridge seismic response study to examine the total submergence, within the domain of water, outside the field of water and other factors on the continuous rigid frame bridge seismic response characteristic cs of impact.
