Assembled prestressed fish bel ied beam steel sup-port in deep foundation pit is applied more and more, thanks to the tool can be used repeatedly, shorten the construction period and other advantages. In this paper, combined with the specific project example, it expounds the construction technology, tec-hnical features, construction cost, enclosure deformation to sta-rt the internal force adjustment scheme, to control and reduce the deformation of beams, provides the engineering examples Shanghai can be extended, also provides a good example for S-hanghai City green construction.
