| 摘 要： | 根据支盘桩抗压、抗拔及抗扭曲的阻抗性能,提出了由支盘桩代替直杆桩,组成支盘桩-地基-上部结构体系,并对该体系进行了理论分析。通过分析认为:支盘与阻尼器具有相似性原理,在地震作用下,盘在土体中作位移极小的往复运动,提供刚度和阻尼、消耗地震能量、减轻地震动对结构的地震反应。针对该体系的抗震特性,提出了相应的计算分析方法和模型试验方法。

| Abstract: | Considering that disk piles possess markedly resistance to compression, extraction and torsion,it is put forward that straight piles can be substituted by disk piles to form a disk pile-soil-superstructure system.It is thought that the working principle of disk piles is similar to that of dashpots. The disks move back and forth in the soil with small displacement under the seismic action,which provides rigidity and damping, depletes the seismic energy,and lightens the seismic action on the structure. The methods of computation and model experiment are introduced for the study of the interaction in the system. |
