Without shaft wheel installation process, the displacement relationship between bar to the quality of the whole project, it throughout the construction period and operation period, the paper mainly discusses the countless shaft simulation method in the process of installation construction technology of the no-shaft ferris wheel, using numerical analysis software MIDAS, to wei-fang whitewater river bridge and the no-shaft ferris wheel engineering simulation analysis, the numerical calculation results show that the height of 138 m without shaft wheel is divided into four parts installation, lower installation uses the ground support, through the heavy crane car component unit installation, USES the lower structure to pass the structure of central pillar support, cooperate with the tower crane and scaffolding, upper installed through the lattice column support, to complete supporting system and operating scaffolding tower, the no-shaft ferris wheel upper nodes maximum displacement of 258 mm, lower part of the minimum displacement of the 54 mm, node displacement less than 1/500 h, the biggest meet construction specification requirements; Provide theoretical numerical reference for similar projects.
