Abstract: The total height of Yincheng Plaza is 80m, which is composed of two parts-main building and auxiliary building. The engineering foundation design and the design characteristics of the main part were introduced, the seismic performance of the overall structure was studied, and calculation models were reasonable selected. The calculation results was analyzed and compared. Some key technical problems were seriously analyzed such as the structural design of super long basement, encountered in pile foundation embedded pipes, partial conversion, and davit and so on, and puts forward the solving methods and strengtheTcung measure were put forward.
Keywords: structure design; super long basement; ground source heat pump; partial conversion; davit
