Abstract

The invention discloses a cable-stayed immersed tube tunnel structure and method, which solves the problem that a large amount of manpower, equipment and financial resources are required for the construction of the immersed tube tunnel structure in the prior art, and has the advantages of being able to effectively adapt to weak riverbeds, seabeds, etc. Geological conditions, beneficial effects of adjustability, the scheme is as follows: a cable-stayed immersed tube structure, including multi-section immersed tubes, and pile foundations perpendicular to the surface of the immersed tubes are fixed on both sides of each section of immersed tubes. The foundation and the immersed tube are connected by a plurality of stay cables, the stay cables are arranged symmetrically on both sides of the pile foundation, and the stay cables are arranged obliquely.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to the construction of underwater tunnels in soft clay or riverbeds and coastal areas, and in particular to a cable-stayed immersed tube tunnel structure and method. Background technique [0002] The immersed tube tunnel structure has the advantages of low cost, short construction period, easy operation and installation, and various cross-section types. It has been widely used in cross-river and sea-crossing projects. However, the immersed tube method is used to build underwater tunnels in soft clay or riverbeds and near-coastal areas. Due to the uneven distribution of strata in riverbeds or near-coastal areas (the mechanical strength of rock-soil medium is weakened from the riverbank or coast to the riverbed or seabed), Placing the same structure on such a stratum can easily cause uneven settlement of the structure as a whole, resulting in cracking of the structure...
