摘　　要：介绍双向振动机的结构及使用该机进行振密试验情况。试验结果表明它比原振冲法成孔快速,加固均匀。用这种机具加固水下软基,振密后的标贯击数可比天然的提高4～5倍。Structure of 'bidirectional vibrator' and the condition of vibro-compaction test by using this vibrator are introduced. The test result shows that:by using this vibrator, holes may be formed faster and consolidated soil more uniform than using the former vibro-jetting method, and the standard penetration blow of the underwater soft foundation after being vibro-compacted & consolidated by this bidirectional vibrator is 4-5 times higher than that of natural foundation.
