【摘要】：为解决长江高填方护岸深厚覆盖层地基的抗滑稳定问题,采用振冲置换法对地基进行加固处理。计算分析表明,振冲碎石桩处理范围、桩间距、桩长等参数应结合地形、地质条件进行设计,振冲置换法与其他地基处理方式进行有机结合能够取得更好的处理效果;护岸地基通过振冲置换处理后,抗滑稳定性能够满足规范要求。采用振冲碎石桩对软弱地基进行置换形成复合地基,能够有效解决地基砂土液化问题、承载力问题及抗剪强度问题。
[Abstract]:In order to solve the problem of anti-slide stability of the deep overburden foundation of the high fill bank of the Yangtze River, the method of vibration and impact replacement is adopted to reinforce the foundation. The calculation and analysis show that the parameters such as the treatment range, pile spacing and pile length should be combined with terrain and geological conditions, and the combination of vibroflotation replacement method and other foundation treatment methods can achieve better treatment effect. The anti-slip stability of the revetment foundation can meet the requirements of the code. The composite foundation can be formed by replacing the soft foundation with vibroflotation gravel pile, which can effectively solve the problems of liquefaction, bearing capacity and shear strength of the foundation.
