Research For Movement Of Cable’s Endpoints Between Double Barges And Immersed Tunnel

Immersed-tunnel method is a kind of construction in building undersea tunnels, and many engineering methods in contemporary connected across straits. The tunnel has become a cost-effective mainstream program, which construction methods to build their research is very important. It is well known undersea tunnel is a tunnel built to connect across straits for vehicle traffic use. Large undersea tunnel can be divided into segments, coast and approach roads of three parts, of which the main part of its undersea section. Subsea segment usually buried at the bottom of the sea bed, its ends connected with the coast, then through approach road, and the ground line is connected, in general, while the construction of tunnel shaft in place on both sides, and is equipped with drainage, electricity and ventilation equipment.The current method of tunnel construction are mainly four kinds, namely, drilling and blasting, tunneling machine method, shield law, as well as to explore this study related to the immersed tube method. In the immersed tube method, barge is widely used, which is about to sink prefabricated tunnel tubes containing shipped to the installation location and then through the cable to sink gradually into the specified location and to ensure its security and stability of its construction process one problem, which this paper and its sinking force during the movement of the cable to explore research. Construction immersed tube sinking process model simulation realistic, as measured by dual-tension sensor barge, double barge sinking pipe coupling through the motor system in different wave conditions force the cable, the six degrees of freedom simultaneously by optical motion detection system motion analysis barges and sink pipe after being converted by the movement of the cable at both ends. Experimentally measured data for comparison, analysis, elements of different waves and sink deep influence of this system and concluded that a similar situation may need to be paid attention to the actual construction of the place.
