摘要：
The reinforcement mechanism of high vacuum compaction method were introduced. Based on engineering project, the construction technology of high vacuum compaction method was introduced. The change law of pore water pressure and settlement were studied by field test, and the process of dynamic consolidation was analyzed. The change of soil parameters were contrasted by cone penetration test and bearing capacity of foundation test in pre- and post of foundation treatment. The feasibility that high vacuum compaction method in improving shallow layer soft soil was verified.
