【摘要】 非等长桩群桩基础的变形性能,可以用在顶端设置一个水平刚臂和一个水平弹簧支承的悬臂立柱来模拟。通过算例的分析结果表明,这种等代计算模型不仅具有较高的精度,而且大大地简化了超静定桥梁结构的上、下部结构整体分析。更多还原

【Abstract】 The deformation behavior of complex pile foundation with non-equilong piles may be simulated by a cantilever column with a horizontal rigid-arm and a horizontal spring hearing on the free end.The analysis results of example expressed that the equivalent calculating model in this paper not only had the higher precision.but also greatly simplified the combination analysis with superstructure and substructure for the statically indeterminate structure of bridges.更多还原
