Abstract The bearing system of full space supports is a multi-fulcrum bearing system. The loads arc scattered through multi-points and transmitted to the foundation. Therefore, it is required that the foundation should have sufficient bearing capacity, so as to render the settlement amount of the supports controlled within allowable scopes during the construction procedure of casting concrete in situ. At the same time, even settlement is required for all fulcrum points to prevent cracks produced on beam's body due to uneven settlements. The technical analyses and summaries concerned with the design, construction and applications of the full space supports arc put forward in this paper.
