振冲碎石桩在地基加固处理中的应用

Application of vertical pile driven by vibration in subgrade reinforcement

某闸地基浅层存在较厚的饱和粉细砂层,导致地基承载力满足不了设计荷载要求、地基土透水性较强易产生流土渗透破坏以及地基难以满足抗震设防要求等问题。针对上述问题,本文详述了振冲碎石桩加固此闸区地基的设计、施工及检测,结果表明本文采用的方法能取得较良好的地基加固处理效果。

The thick saturated silty and gravel strata with poor bearing capacity, strong penetrating and liquefaction are existing in the subgrade of one gate. The vibration piles were applicated to reinforce the subgrade to solve such potential problems. This paper discussed the design, construction and examination of the vibration piles in detail. It is indicated that the vibration piles are effective for ground treatment.
