EFFECT EVALUATION OF TREATMENT ON COASTAL LIQUEFIABLE GROUND USING RESONANT COMPACTION METHOD

On the east coast in our country, there are many Coastal liquefiable ground. This kind of groud compared with general liquefiable ground, there are more clay interlayer. The resonant compaction method with crisscross section vibratory probe as a new method of liquefiable ground treatment, whether in the processing of Coastal liquefiable ground has good processing effect, is a focus in the study of this article. Combining the use of resonant compaction method in highway of HuaiYan(Dafeng port section) project, I judge the treatment with methodsof SPT and CPT, both of before and after the treatment. Results show that the resonant compaction methodwith crisscross section vibratory probe can achieve good treatment effect in Coastal liquefiable ground. This method has good application prospect.
