摘要
各种桩基深基础都是依靠桩身与周围土体相互作用产生的侧摩擦力与基底反力来实现垂直承载力的,在施工过程中如扰动了原状土就会产生群桩效应降低承载力。通过工程实践证明钻孔灌注桩施工工艺不改变原状土性,不产生群桩效应。
Vertical pile capacity of various pile foundations are achieved through the effect of laterel friction along the piles and end-bearing capacity of piles.During the construction period,bearing capacity of the piles would be reduced by the action of pile group,if the undisturbed soil is remoulded.The construction practice proves that the construction method of bored cast-in-situ pile will not bring about the action of pile group.
