According to the idea that the larger the area occupied by the tower base, the greater the load bearing capacity or the lower foundation bearing capacity required, the main design idea is to take the continuous slab or beam slab reinforced concrete foundation on the soil as the supporting point, and form a platform by setting the plate surface and pier to provide the support point for the tower foot, forming a new type of new type suitable for the high water level area with poor bearing capacity The foundation type is especially suitable for the tower location with limited tower location and insufficient bearing capacity, foundation excavation is very difficult, cast-in-place pile construction is difficult to solve or the economic performance index is not good. This paper studies the technical characteristics of raft foundation and the possibility of its application in this paper. Through the calculation and analysis of typical tower type, the economic and technical comparison with plate foundation is made. Finally, the application suggestions of raft foundation in this paper are put forward.
