十字振动翼共振法处理滨海相可液化地基的效果评价

在我国广大的东海岸上, 存在着较多的滨海相可液化地基。这种地基相较于一般的液化地基, 存在着较多的黏土夹层。十字振动翼共振法作为一种新的液化地基处理方法, 能否在滨海相可液化地基的处理中取得较好的处理效果, 是本文研究的重点。本文通过结合采用十字振动翼共振法的淮盐高速(大丰港段)工程实例, 在对该场地进行液化地基处理后, 采用标准贯入试验测试以及静力触探测试对处理后的地基进行抗液化评价。结果表明在较为复杂的滨海相可液化地基上, 十字振动翼共振法能够取得良好的处理效果。该工法具有良好的应用前景。

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.
