The invention relates to the technical field of civil engineering, in particular to a three-dimensional static calculation method for an overhead pile plate structure, which comprises the following steps establishing a three-dimensional static model of the pile plate structure; inputting the load parameters into the three-dimensional static model of the pile plate structure, and outputting a deformation result and a stress result of the pile plate structure; and checking the deformation result and the stress result, and determining final structure parameters of the pile plate structure. According to the three-dimensional static force calculation method of the overhead pile plate structure, the three-dimensional static calculation of the overhead pile plate structure is realized, the load parameters are input into a three-dimensional static model of the pile plate structure, the deformation result and the stress result of the pile plate structure are output, the three-dimensional spacedeformation, multi-directional stress and stress concentration conditions of the structure can be reflected, comprehensive and detailed calculation data and results are provided for designers, and thefinal structure parameters of the pile plate structure are determined by checking the deformation result and the stress result.

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-slab structure. Background technique [0002] The pile-slab 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 treatment method of pile-slab structure + soil filling is often used . This traditional subgrade structure of "pile-slab structure + soil filling" has problems such as large foundation treatment area, land occupation width several times the width of the subgrade surface, a large amount of subgrade filler, and high construction cost. Therefore, some people based on this structure A new type of roadbed structure is proposed-the overhead pile-slab structure. This structure is a new type of roadbed structure with no filler, no spoil...
