To make the Bauhinia Park View Tower in Changzhou-the special ring-shape Ferris wheel construct successfully, the paper researched the installation and process control method which was based on the theory of process control. The cantilevered symmetrical installation method was adopted and the process control scheme was implemented by prestressing the structure, with the help of masts and cables and other auxiliary facilities. The main principle of the process control was to control the whole shape after construction. Besides, the structure internal force was controlled. In addition, the efficiency of process control must be higher. The process control scheme was devised, and then the secondary development technology based on ANSYS was applied to iterative calculate the cables tension. By time-varying simulating and analysis, it indicated that the deformation after construction met the controlled demand. The internal force during installation and after construction met the demand of bearing capacity.
