As the construction needs to cross more and more existing railways and other obstacles, the swivel technology is widely used in various bridge projects. Based on the engineering background of a double swivel railway bridge, this paper analyses the construction monitoring scheme of this kind of bridge in the following three aspects. Firstly, the swivel environment should be fully considered when formulating the swivel plan. Secondly, the construction schemes of hanging basket, spherical hinge, weighing, bob-weight and traction cable are discussed. Thirdly, cantilever end superelevation monitoring and rotation process angle monitoring has been discussed in the application technology of double swivelling body project. Meanwhile, the three-dimensional laser scanning technology is compared and analyzed with commercial technology. The conclusion shows that 3D technology has advantages over total station monitoring in swivelling body monitoring. Furthermore, it realizes the application of various data monitoring of rotating body, to achieve the purpose of accuracy algorithm optimization.
