大厚度饱和砂土液化地区振冲桩施工工艺试验研究
摘要:针对大厚度饱和砂土液化地基,采用振冲碎石桩方案,分析不同型号振冲器成桩效果,试验不同的成孔辅助方式和成桩填料方法,对"抱孔"、振冲器掉落和虚高等施工常见问题进行分析和预防处理,探讨施工工艺合理性,提高施工效率,降低安全风险,为类似工程提供一定参考借鉴。
Abstract:The program of gravel piles with vibroflotation is used to handle the liquefaction of large-thickness saturated sand foundation. In this program, the pile effect of different types of vibrator is discussed, the different pore-forming auxiliary ways and pile filler methods are tested, frequently asked questions in construction, such as "holding hole",vibrator fallen,virtual height etc., are analysed and the preventive measures are suggested in order to discuss on the construction process, improve construction efficiency, reduce security risks, provide some reference for the similar engineering.
