【摘要】 本文根据弹性地基梁理论建立力学模型，借用水平面弯曲梁传递矩阵，结合《公路桥涵设计规范》桥梁群桩的计算假定，建立了一套精确而实用的，非常适合于微机计算的桥梁桩基础内力的计算公式，经示例计算，证明本方法解析桥梁桩基础精确、可靠，可供工程实际设计采用。更多还原

【Abstract】 The author has estaalished a mechanical model based on the theory of elastic foundation beamsand derived a useful formula for calculating the internal forces of a pile group,using transfer matrixof curved beams in horizontal plane. The derivation is also based on calculation assumptions for pile-group foundations of bridge structures given in relevant bridge specifications。更多还原
