应用密集桩复合地基应注意的几个问题

近年来挤密桩在地基加固工程中应用较广,根据本人在实际工作的经验,灰砂石挤密桩复合地基主要是靠桩管打入地基时对软弱土产生横向挤密作用,从而使土的压缩性减小,抗剪强度提高,应用时应注意桩的布置、采取合理的设计计算方式、施工时对地基土的含水量的控制以及严格的试验与检验等几个问题。

Applied a Few Question that the Compaction Pile Compound Foundation Should Notice

In recent years the lime-soil compaction pile is in foundation reinforce engineering the application compare widely,according to oneself in the actual aperative experience,the lime-soil compaction pile composite foundation mainly is to is take care of by stake to beat into the foundation living the transversal compaction pile action to the weak local product,thus make the compressibility of the soil reduce,shear strength exaltation,notice the stake to arrange while applied,the design that adoption is reasonable calculate way,construction hour to the foundation soil control with amount of water and a few questions such as strict teat and inspection etc.
