可变式支盘扩底植入桩试验研究

介绍了挤土桩、非挤土桩、部分挤土桩各自的成桩原理及其局限性。可变式支盘扩底植入桩属于部分挤土桩，其可行性试验结果表明，这是一种承栽力高、适用范围广、质量易于控制、节约造价、工期短、施工噪声低的新型桩型。

Experimental Investigation of Variable Back Plate Pedestal Imbedded Pile

This paper introduces the pile- formation principles and the li mi tations of the densification by soil pile, non- densification by soil pile and partial- densification by soil pile, and the variable back plate pedestal imbed ded pile belongs to the partial- densification by soil pile, the feasibility te st results shows that this kind of pile is a new one with higher load- bearing capacity, wider scope of application, higher quality, lower construction cost, s horter construction period and lower construction noise.
