摘要
文章以实际工程为例,运用ANSYS三维有限元软件对高桩墩台码头进行不同计算方法下的内力对比分析,得出3种(弹性嵌固法、M法、P-Y曲线法)不同计算方法下高桩墩台结构的桩基内力值及分布情况,总结出如下结论:(1)桩身弯矩最值发生在桩头或嵌固点处,设计时注意在这些地方对桩基进行局部加强;(2)当地质资料不是很详细时,可优选采用弹性嵌固法进行计算,其计算结果对土体参数选取不太敏感。
Based on specific engineering, ANSYS(3-D finite element software) was applied to calculate and an-alyze the internal forces of dolphin wharf in different calculation methods, including elastic embedded method, Mmethod and P-Y curve method. Values and distribution of pile internal forces in the three calculation methods wereobtained. The main conclusions are as follows:(1)the limit value of pile bending moment is at the pile head or fix-ing point, so local strengthening should be taken into account in pile design.(2)In the case of lacking geologicaldata, elastic embedded method is recommended, since the results of this method are not sensitive to soil parameters.
