| 摘 要： | 本文通过有限元方法和简化算例分析了带斜桩的群桩工作特点,计算分三种情况:(1)群桩只承受竖向和水平的荷载,没有地面位移;(2)群桩承受竖向和水平荷载作用的同时,还承受水平地面位移;(3)群桩承受竖向和水平荷载作用的同时,还承受竖向地面位移。计算结果表明:当地面发生水平或竖向位移时,设置斜桩对群桩承载能力有一些不利影响。

| Abstract: | Some characteristics for a pile group containing raked piles were studied by finite elment method and some simplified examples. Three cases are analysed: (1) a pile group subjected to vertical and lateral loadings, with no ground movements; (2) a group subjected to vertical and lateral loadings, but with horizontal ground movements; (3) a group subjected to vertical and lateral loadings, but with vertical ground movements. It was found that raked piles can provide some disadvantages to the bearing capacity of a pile group when the group was affected by ground movements acting on the pile group. |
