【摘要】 通过工程实例,介绍了砂土地基采用振冲碎石桩进行处理的施工工艺、施工参数、施工过程的质量控制,以及对处理后的桩体、复合地基、砂土液化消除情况进行的工程质量检测。质量检测表明,桩体密实,质量较好,经振冲碎石桩处理后的复合地基承载力特征值不小于250 kPa,满足设计要求,处理范围内砂土的液化已全部消除。更多还原

【Abstract】 This article by project instance,describes the use of sand foundation stone for processing of construction technology,construction,construction quality control,as well as on the pile after processing,composite foundation,liquefaction of elimination of project quality testing.Quality testing suggests that the pile of dense, the quality is good,Vibro after compound foundation eigenvalue is not less than 250 kPa,meet the design requirements,process-wide sand of liquefaction has been eliminated.更多还原
