Problems solved by technology

With the continuous development of China's marine resources to the deep sea, the construction of submarine tunnels will surely usher in a period of accelerated development. However, the traditional foundation reinforcement technology can no longer guarantee the stability of the foundation of deep-sea submarine immersed tunnels, which restricts the development of immersed tunnels. and application

Abstract

The invention discloses a cable-stayed immersed tunnel structure and a method, and solves the problem in the prior art that a great quantity of manpower, equipment and financial resources need to be input for immersed tunnel structure construction. The cable-stayed immersed tunnel structure has the beneficial effects that the cable-stayed immersed tunnel structure can be effectively suitable for bad geological conditions including soft riverbeds, seabeds and the like and is adjustable. The cable-stayed immersed tunnel structure has the following scheme that the cable-stayed immersed tunnel structure comprises multiples sections of immersed tubes, wherein two sides of each section of immersed tube are respectively fixedly provided with a pile foundation vertical to the surface of the immersed tube; the pile foundation and the immersed tubes are connected through multiple stay cables; the stay cables are symmetrically arranged on two sides of the pile foundation and are aslant arranged.

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...
