Abrégé

A submerged floating tunnel full hydroelasticity response model test device and method, relating to the technical field of tunnel engineering. The test device comprises a submerged floating tunnel model (1), a support device and a test pool (10). The support device comprises end supports (4) and temporary support frames (5), the end supports (4) and the temporary support frames (5) being respectively connected to two ends and the lower side of the submerged floating tunnel model (1). A plurality of anchoring devices (2) are mounted on the submerged floating tunnel model (1) in the length direction thereof, one end of each anchoring device (2) being connected to the submerged floating tunnel model (1), and the other end of each anchoring device (2) being anchored to the pool bottom (1002) of the test pool (10). The submerged floating tunnel model (1) comprises test segment pipe sections (101) and mounting segment pipe sections (102), two ends of each test segment pipe section (101) being respectively provided with a recessed part and a raised part, and the recessed part of each test segment pipe section (101) being in mated connection to the raised part of an adjacent pipe section. The test device may completely reproduce an internal structure of a tunnel, solves the problem of a traditional submerged floating tunnel model test that a model is not similar to a prototype tunnel, and may achieve simulation of structurally-complete hydroelastic motions and deformations of pulling, pressing, bending, shearing, twisting and a combination of various states of a tunnel.

Abrégé

The present disclosure relates to the field of basic equipment for underwater tunnel transportation, and in particular to a tube joint apparatus for a double-tube floating tunnel, and a construction method thereof. The apparatus comprises joint devices, tunnel tubes and escape devices. The escape devices are arranged inside the joint devices. The tunnel tubes are respectively connected to the left and right ends of the joint devices. Multiple anchor yokes are connected to the outside of the joint devices. The connection devices comprise watertight locking structure sections, framework connection sections and main body function sections. The main body function sections comprise joint inner road surfaces and joint housings. The joint inner road surfaces are arranged inside the joint housings. The watertight locking structure sections are respectively connected to two ends of the framework connection sections. Compared with a traditional floating tunnel joint device which can only achieve a single function, the present invention increases the utilization rate of the internal space of the underwater floating tunnel, significantly reduces the complexity of the entire linear structure system of the floating tunnel, improves the connection strength of the tunnel tubes and the joints, and reduces the safety risk of the tunnel.

Abrégé

The present invention relates to the technical field of tunnel engineering, and in particular to a floating tunnel rail automobile-carrying system, and an automobile quick-passage method. The floating tunnel rail automobile-carrying system comprises land traffic sections and a submerged floating tunnel section, wherein two land traffic sections are respectively arranged at an entrance and an exit of the submerged floating tunnel section; each land traffic section is at least of a double-tier structure, an upper tier being an automobile pavement tier, and a lower tier being a rail tier; rails are laid on the rail tier; a vehicle carrying platform supply station and a serving station are provided at ends of the rails; and the submerged floating tunnel section is of a tubular structure, and comprises a tunnel main body and a slope section. According to the present invention, the technical advantages of traditional road and railway transportation modes are combined, and automobiles can be rapidly transported from one side to the other side of a deep water strait by means of rails, such that the passage capability of the floating tunnel is greatly improved, thereby improving the efficiency of the transport of people and materials and greatly relieving the sense of repression when driving in an enclosed space for a long time for improved driving comfort.
