摘　　要：十字翼共振法作为一种新型液化地基处理手段,现已逐步在南方地区的众多工程项目中得到实施与应用。为了进一步研究十字翼共振法加固可液化地基的效果,本文根据洋通高速工程中十字翼共振法的应用实例,系统梳理了该方法的具体施工流程;同时通过实施标准贯入试验与静力触探试验,对处理后的地基进行了全面而精准的评价。结果表明:使用十字翼共振法处理后,试桩各区的试验检测结果均为不液化或轻微液化,可液化地基的密实性得到了很大的提高,整个试桩区经过整平碾压后的平均沉降量为63.9cm;十字翼共振法与传统的砂土液化地基处理方法相比,展现出了显著的优势与优越的处理效果以及良好的经济效益和施工前景,为地基处理领域的发展提供了有力的技术支撑。As a new type of liquefied foundation treatment method,the cross-wing resonance method has been gradually implemented and applied in many engineering projects in the southern region.In order to further study the effect of cross-wing resonance method on strengthening liquefiable foundation,this paper focuses on the application example of cross-wing resonance method in Yangtong Expressway project,and systematically combs the specific construction process of this method.At the same time,through the implementation of standard penetration test and static cone penetration test,a comprehensive and accurate evaluation of the treated foundation was carried out.The test results show that after the treatment of the cross-wing resonance method,the test results of each area of the test pile are non-liquefied or slightly liquefied,and the compactness of the liquefiable foundation has been greatly improved.The average settlement of the whole test pile area after leveling and rolling is 63.9 cm.Compared with the traditional sand liquefaction foundation treatment method,the cross-wing resonance method shows significant advantages and good treatment effect,showing good economic benefits and construction prospects,and providing strong technical support for the field of foundation treatment.
