大直径扩底桩(墩)在我国已得到广泛的应用,其设计计算方法目前仍沿用传统的单一极限应力设计方法,有许多不合理之处。本文根据近几年的研究成果,参考国外一些设计理论,提出一套适合我国具体情况的大直径扩底桩(墩)在变形和极限应力双控制条件下的设计方法。
Large-diameter enlarged piles (piers) have been widely used in China, and their design and calculation methods still use the traditional single ultimate stress design method. There are many unreasonable points. Based on the research results of recent years, with reference to some foreign design theories, this paper proposes a set of design methods for large-diameter, enlarged-bottom piles (piers) that are suitable for the conditions of our country under the dual control conditions of deformation and ultimate stress.
