pile body

Greater changes take place in the bending moment diagram of the rear-pile body when the length of the rear-pile decreases, yet the changes have little effect on the whole retaining and protecting structure;

适当减小后排桩桩长时，后排桩桩身弯矩分布变化较大，但对整体支护效果并不产生较大的影响；

Squeezed branch pile is a kind of variable section pile, which is formed by setting branch or bearing plate on the pile body in the original basis of bored pile.

挤扩支盘桩是在原有的等截面钻孔灌注桩的基础上在桩身设置分支或承力盘而形成的变截面桩。

For in-depth analysis of loading transfer and bearing capacity property on pile body, preliminarily we had arranged rebar stress gauge on trial pole main reinforcement to measure pile body axial stress and inbuilted stress box under the pile to survey tip resistance.

为了进一步分析桩的荷载传递和承载力性状，预先在试验桩主筋上布置钢筋应力计以测量桩身轴向应力，在桩底埋设压力盒以测量桩端阻力。

Wave form interpretation for the structural integrity testing of the pile body by P. I. T. method

P.I.T.法桩身结构完整性测试的波形判读

Then the bearing capacity of composite foundation is significantly increased because of the side friction force and terminal resistance force to the pile body.

由于天然地基土对桩体的侧摩擦力和端阻力的共同作用，使复合地基的承载力大幅度提高。

The model calculation of pile in the test pile project in power plant shows that preconditioned by the assurance of capacity, the optimal design variables can reduce the volume of pile body.

通过某电厂试桩工程成果进行计算分析，结果表明优化设计变量在满足承载力的条件同时较原设计减少桩身体积，降低工程造价，有较好的应用价值。
