Cable-stayed structure system for underground large-span space and design method thereof

Abstract

The invention belongs to the technical field of underground structures, and particularly relates to a cable-stayed structure system for an underground large-span space. The cable-stayed structure system involves an underground structure top plate, bridge towers, tensioning pieces and anchors, wherein the underground structure top plate is connected with the bridge towers through the tensioning pieces; one sides of the bridge towers are connected with the underground structure top plate through the tensioning pieces; the bridge towers can be fused with a ground building to form a ground landscape, entrance-exit spaces are formed in the sides, away from the underground structure top plate, of the bridge towers, the tops of the entrance-exit spaces communicate with the ground, and the bottomsof the entrance-exit spaces communicate with the underground large-span space below the underground structure top plate. The invention further provides a design method of the above cable-stayed structure system for the underground large-span space. According to the cable-stayed structure system for the underground large-span space, the bridge towers, the tensioning pieces, the anchors and the underground structure top plate are adopted to form the cable-stayed structure system for the underground large-span space, earth covering loads acting on an underground structure on the underground structure top plate are transmitted to the bridge towers through the tensioning pieces, and a stress balance system is formed through the anchors so as to build a larger-span underground space, so that the underground space is wider.

Description

technical field [0001] The invention belongs to the technical field of underground structures, and in particular relates to an underground large-span space cable-stayed structure system and a design method thereof. Background technique [0002] Due to the natural isolation between the underground space and the ground space, insufficient natural lighting, lack of natural ventilation, excessive heat and humidity, congenital deficiencies in space network construction and artistic processing techniques, it is easy to produce a feeling of depression and closure, which leads to users' emotions. Tendency to be "unfamiliar" and "away". Therefore, the future development of underground space can build a new structural system such as large-span space through the integration of above-ground and underground space, so as to improve the comfort of underground space and expand the use function of underground space. [0003] At present, the underground structures used for underground long-s...

AI Technical Summary

Problems solved by technology

[0003] At present, the underground structures used for underground long-span spaces mainly include flat-roofed orthogonal beam structures, folded plate structures, and arched structures. To achieve a larger span, it is necessary to increase the beam height, increase the depth of the underground project, affect the beauty of the underground project, and increase the project investment
