［摘要］在9度設防區(qū)對某多塔樓圍合式形成的大底盤多塔樓建筑進行隔震設計時，受建筑功能限制，不能在大底盤之上設置隔震層，而是采取在大底盤下設置，目前國內尚無先例。針對大底盤下設置隔震層遇到的特殊問題作了分析探討，提出加強隔震層樓面剛度的措施，設定罕遇地震作用下隔震層樓板不屈服的性能目標，并進行了罕遇地震作用下圍合中庭樓板破壞工況的驗算，確保罕遇地震作用下隔震層不破壞。
［關鍵詞］大底盤；隔震層；剛度；彈性

Abstract:In the design of a multi\|tower building with large base in area of 9 degree seismic precautionary intensity, seismic isolation layer can not be applied above the large base due to the architectural function demand, while it was applied beneath the large base, and this is unprecedented in domestic. The special issues encountered in applying seismic isolation layer below the large base were analyzed. The rigidity of seismic isolation layer floor was enhanced, and unyieldingness performance objective of seismic isolation layer under rare earthquake action was presented. The damage cases calculation were carried out to ensure no seismic isolation layer damage under rare earthquake.
Keywords:large base; seismic isolation layer; rigidity; elasticity
