APPLICATION OF TREATMENT ON LIQUEFIED FOUNDATION USING RESONANCE COMPACTION METHOD

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.
