| For implementing the national petrochemical industry layout, advancing the building of Dalian Changxing Island Petrifaction Park and promoting local industry and economic development, the Hengli petrifaction project arises at the historic moment. A 100 thousand tons berth is planned meet the needs of enterprise production of raw material transportation. The high-piled bent structure is adopted for working platform and the high-piled pier structure is used in mooring and trestle design.Because of its good adaptability to soft ground, high-piled wharf has a wide range of applications in engineering. There will be a difference between the force of the simplified plane calculation and the actual structure, for the stress characteristic of high-piled wharf structure is spatial. Plane calculation method is usually adopted for high-piled wharf design, i. e., to calculate the interal force of structure in the transverse and longitudinal plane directions, in which, transverse bents are calculated as flexible platform and longitudinal girders as elastic supporting continuous girders.But when the transverse and longitudinal stiffness of the pier is close and the spatial characteristic is more remarkable, the space calculation method is more reasonable for the pile structure. With the development of spatial calculation methods and means, appropriate calculation model can be selected according to the specific situation in the project.At present, the mature high-piled wharf structure calculation software mostly adopts plane finite element analysis method, which may be easily used and spread compared to general finite element program, but the scope of application is limited. In this project, the high beam slab structure is adopted for the working platform, which has a high longitudinal stiffness and load. So the usual plane finite element analysis program is not applicable. Therefore, the general finite element calculation program ABAQUS is used for structure calculation in this design. |
