摘要
筏板基础已被广泛应用于高层建筑中,鉴于其受力复杂、受力机制还不清楚,目前对于筏板厚度的确定存在很多不合理的地方,用有限元计算方法和共同作用设计方法,通过分析不同厚度条件下筏板基础的受力、变形情况,得出受力及变形规律,为工程实际设计提供有效参考。
The raft foundation has been widely applied to tall building, in consideration of the stress state is complex and the stress mechanism is unclear, there are many unreasonable problems while deter- mined the raft thickness at this stage. This paper used the finite element method and the interaction de- sign method, on the basis of analysis of stress and deformation under the condition of different raft thick- ness, get the raft stress and deformation principle, provides a reference experiences to practical design.
