    十字形振动翼共振法在处理可液化地基中的应用

    APPLICATION OF TREATMENT ON LIQUEFIED FOUNDATION USING RESONANCE COMPACTION METHOD

    • 摘要: 目前国内外处理液化地基的方法很多,如换填法、强夯法、振冲碎石桩法、振冲砂桩法、振密法等,每种处理方法都有它的适用范围和局限性。共振法与其他液化地基处理方法相比,该方法无需用砂石骨料置换部分的地基土体,施工方便,加固效果显著,在国外得到了广泛的应用。本工程通过考虑场地工程概况、施工条件、经济技术条件等,采用十字翼共振法对该场地进行液化地基处理,用不同测试方法对处理后的地基进行抗液化评价。处理后通过静力触探测试和标准贯入试验测试,结果表明,十字形振动翼共振法可有效加固可液化地基,消除液化; 且设备简单,操作方便,施工效率高,造价相对其他加固方法低,对环境振动影响小,具有良好的应用前景。

       

      Abstract: At present domestic and foreign processing method of liquefaction is in a large number, such as the replacement method, dynamic compaction, gravel pile method, Zhen Chongsha method and compaction method. Each method has its scope and limitations. Compared with other methods in treatment of liquefiable ground, resonance method needs no aggregate replacement, convenient for construction, good strengthening effect, which has been widely used in abroad. By considering the site engineering, construction condition, economic and technological conditions, use cross wing resonance method to conduct liquefied foundation treatment.liquefaction evaluation on treated ground for different test methods. After processing the test, static cone penetration test and standard penetration test results show that, vibrating wing resonance method can effectively reinforce the liquefaction, liquefaction elimination; and has the advantages of simple equipment, convenient operation, high construction efficiency, low cost compared with other strengthening methods. The environmental impact of small vibration, and has a good prospect of application.
