The vibroflotation was a method only for strengthening foundation before.
以往振动水冲法只是一种加固地基的方法。
The range of liquefaction is limited so that sand liquefaction does not cause slide failure during vibroflotation.
液化的范围是有限的，因而振冲时砂土液化不会造成坝坡坍滑。
The vibroflotation sand compaction pile is an economical, reasonable ground treatment method, and it is recommended to use in this substation foundation.
