摘　　要：提出了一种新型偏心装配式基础,该基础采用穿钉贯穿固定基础构件来满足受力要求。为研究新型偏心装配式基础力学性能,建立相同尺寸的现浇偏心基础及偏心装配式基础有限元模型,分别研究相同上拔荷载及下压荷载作用下两种基础云图及底板测点应力曲线,并对新型偏心装配式基础穿钉进行验算。研究表明:在相同荷载作用下,两种基础的应力云图及应力曲线变化趋势相似,新型偏心装配式基础各装配件荷载传递由穿钉承担,且能满足偏心基础力学性能要求。In this paper,a new type of eccentric assembled foundation is investegated,employing Nail-through fixed foundation members to satisfy the loading conditions.To examine the mechanical properties of the new eccentric assembled foundation,finite element models for both cast-in-situ eccentric foundation and eccentric assembled foundation of the same size were established.Two types of foundation nephogram and stress curve at measured point on the bottom plate were analyzed under identical uplift and downward pressure loads.Additionally,a checking calculation for the new eccentric assembly foundation nailing was conducted.The stress nephogram and stress curve of both types of foundation are similar,indicating that the load transfer for each part of the new eccentric assembly foundation is facilitated by piercing,and it meets the mechanical performance requirements of an eccentric foundation.
