摘要 南水北调中线安阳段总于渠横跨于安阳河北侧古河道上,古河道的河床上沉积层为饱和液化软土,为了渠基的稳定,采用振冲碎石桩消除软土液化。本文从振冲碎石桩的机理、影响因素、施工参数的选定、施工工艺及方法、标准贯人检测等方面,介绍了该方法在渠基处理中的应用。 The main trunk canal of the Anyang section in the Middle Route Project of the South-to-North Water Transfer stretches across on the ancient riverbed north to the Anyang River. The deposit of the riverbed is saturated liquefied soft soil. To the stability of the canal base, vibro- flotation stone pile method is adopted to produce composite ground and eliminate the liquefied soft soil. The paper introduces the method applica- tion in the treatment of the canal base from the principle, influencing factor, construction parameters designation, construction craft and method, standard penetration test.
