桩群中设置斜桩对其工作性质影响的研究

通过FORTRAN语言程序及算例,分析了在桩群中设置斜桩所引起的一些现象.重点对三种典型荷载情况进行了研究,每种情况下都分析了斜桩对群桩沉降,水平位移和转角,桩的荷载和弯矩的影响.结果发现,当桩群承受竖向和横向荷载时,斜桩的存在有一定的好处,尤其在减小水平位移方面.但当有竖向或水平土体位移作用在桩群时,群桩的工作特性会受到不利影响.

Study on Effects of Construction of Raked Piles in a Pile Group

With the adoption of FORTRAN program,some of behavioral characteristics of pile groups containing raked piles,via a simplified and hypothetical example,are examined.Three cases of tests are studied.In each case,the effect of pile rake on typical behavioral characteristics(group settlement,lateral deflection and rotation,and pile loads and moments) are analyzed.It is found that,while the presence of raked piles can provide some advantages when the group is subjected to vertical and lateral loadings,especially in relation to a reduction in lateral deflection,some aspects of group behavior may be adversely affected when either vertical or horizontal ground movements act on the group.
