Research on Construction Process of the Cable-net Structure of FAST

Abstract

With a huge collecting area of more than 30 football fields, Five-hundred-meter Aperture Spherical radio Telescope (FAST) is the largest single dish in the world. There are many construction methods of large span cable-net structures some of what is very complicated, so the distribution of internal force of structures is intricate and alternative. According to a variety of mechanical problems and technical difficulties existing in the construction process determine the general construction scheme of the podium, through simulated the construction process, optimize the construction program. The research showed that it had no effect on the structure to consolidate part of the construction steps of theory construction scheme, the actual construction scheme to be used is safe and feasible, and the important conclusion that cable crane and V-zone system are safe is arrived.
