［摘要］內蒙古大東方廣場上部結構偏置，荷載不均勻，基礎差異沉降量大，上部結構具有扭轉不規(guī)則、樓板不連續(xù)及塔樓偏置等多項不規(guī)則，屬于超限高層建筑。結合其設計過程，討論了基礎設計概況，針對上部結構超限情況，采用基于性能目標的抗震設計方法，討論了結構不同部位的抗震等級。通過大量的計算分析以及嚴格的抗震措施，確保了結構在地震作用下具有良好的抗震性能。

Abstract: Leaning upper structure, uneven distribution of load, large differential settlement of the foundation, torsion irregularity, discontinuity of floor slab, upper structure bias are main characteristics of Inner Mongolia Oriental Plaza, it is a special irregular high-rise building. Based on the structure design process, the general design of foundation was discussed，for the conditions of beyond code limits, the performance-based seismic design method was adopted, the concept of different parts of the structure with different seismic grade was proposed。Seismic performance is ensured through lots of calculation analysis and strict aseismatic measures.
Keywords: CFG (cement-flyash-gravel pile) composite foundation; super high-rise building; structural irregularity items; elastic-plastic analysis; construction measure
