Abstract

The invention relates to the technical field of civil engineering, in particular to a three-dimensional static calculation method of an overhead pile-plate structure, comprising the following steps: establishing a three-dimensional static model of a pile-plate structure; inputting load parameters into the three-dimensional static force of the pile-plate structure model, and output the deformation and stress results of the pile-slab structure; check the deformation and stress results to determine the final structural parameters of the pile-slab structure. The three-dimensional static calculation method of the overhead pile-slab structure described in the present invention realizes the three-dimensional static calculation of the overhead pile-slab structure, inputs the load parameters into the three-dimensional static model of the pile-slab structure, and outputs the deformation of the pile-slab structure. The results and force results can reflect the three-dimensional deformation, multi-directional force and stress concentration of the structure, and provide designers with comprehensive and detailed calculation data and results. By checking the deformation results and force results, Thereby, the final structural parameters of the pile-sheet structure are determined.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a three-dimensional static calculation method of an overhead pile-plate structure. Background technique [0002] The pile-sheet structure is a common and mature foundation treatment method in railway subgrade engineering, which can well control the post-construction settlement of the railway track structure. For the filled embankment section, the pile-sheet structure + filling method is often used. . This traditional subgrade structure of "pile-plate structure + filling" has the problem of large foundation treatment area, the width of the land is several times the width of the subgrade surface, a large amount of subgrade filler is required, and the construction cost is high. A new type of roadbed structure, the overhead pile-slab structure, is proposed. It has the characteristics of good integrity, controllable construction quality, and long-term effective control of ...
