摘要

Through the subterranean layer's floor height and beamless slab's height, SPS, Top-Down method, we should check up the economical slab structure form. According to Patand method, Horizontal materials support method, Erect structure's minimum, buildings beforehand construction, core and lamp construction method we can choose the Top-Down method and through the construction site example's economical choose the right method. For example cut down the time limit for the project and reduce the subterranean layer's height, the cost of the basement so that achieve the reasonable structure form.
