Chinese Academy of Sciences, National Development and Reform Commission and the Xinjiang Uygur Autonomous Region will unite together to construct a large all-movable radio telescope which has an aperture of 110m diameter in the county of Qitai. It will be the largest all-movable radio telescope on the ground to achieve the most advanced level in the world after it is put into use. Yet if such large radio telescope is built, the most prominent problems from the structure techniques are listed as follows. There are several improper points in the conventional structure style. Only the gravity load seriously reduces the reflector surface precision (which is called as RMS for short, Root Mean Square) and restricts its performance. Meanwhile, many kinds of upwind profiles cause complicated wind pressure distribution to reflector surface. Moreover, non-uniform temperature deformation caused by solar effect inevitably affects the RMS surface, especially solar cooker problem in the secondary reflector because of the electromagnetic wave focusing also should be paid attention to.
