小桩距组合墩基础的探讨

Discussion on Built Pier of Grouped Column with Small Pile Bay

小桩距组合墩以其复合实体的工作性质与大直径人工挖孔桩相比 ,具有节约工程造价和可采用机械化施工以提高施工速度等优点 ,在一定条件下具有良好的应用价值。本文对小桩距组合墩结构的适用条件和布桩原则、群桩的极限承载力计算及沉降计算等设计问题进行了探讨。

The built pier of grouped column has the property of entity working. It is more advantageous than the large size hand dig pile in reducing engineering cost, raising the level of construction mechanization and construction tempo. In this paper, the problems of conditions for application, principles of pile distribution, calculation of ultimate bearing capacity and settlement of grouped column structure are discussed.
