利用一个产生水平向振动的管状设备在高压水流的帮助下，边振边冲使松砂地基变密，或者在软弱粘性地基中成孔，在孔中填入碎石制成一根根柱体，被体和原来的粘性土构成承载力比原地基高、压缩性比原地基小的复合地基，这种加固技术称为振动水冲法，简称“振冲法”．振冲法所用 Using a tubular device that generates horizontal vibration with the help of a high-pressure water flow, the edges of the loose sand are compacted while oscillating, or holes are formed in the weakly viscous foundation, and gravel is filled into the holes to form a root cylinder. The cofferdam and the original cohesive soil constitute a composite foundation with higher bearing capacity than the original foundation and less compressibility than the original foundation. This reinforcement technique is called vibrating water erosion method and is abbreviated as “vibration erosion method”. Vibration method used
