论述了饱和砂土地震液化的危害,采用挤密砂石桩法消除液化的机理及其在南水北调渠道地基处理中的应用。主要从挤密砂石桩处理液化地基的工艺试验、工艺流程和施工方法等几方面进行了阐述,并通过对处理后的地基进行试验与检测,检测结果表明:能达到消除液化的目的。作为一种经济、有效的地基液化处理方法,值得推广应用。
The harm of liquefaction of saturated sand by earthquake liquefaction, the mechanism of eliminating liquefaction by compacted sand pile and its application in the treatment of channel of South-to-North Water Diversion Project are discussed. Mainly from the compaction sand pile treatment of liquefied ground in several aspects of process testing, process flow and construction methods are described, and through the test of the treated foundation and testing, test results show that: to achieve the purpose of eliminating liquefaction. As an economical and effective foundation liquefaction treatment, it is worth popularizing and applying.
