根据国内外经验表明,振动水冲法用于加密砂基,提高砂基抗液化性能,质量好,费用低,效果显著,可逐步推广使用。 振动水冲法用于软粘土地基,根据我国少数实践和参照国外经验,只要粘土的不排水抗剪强度不低于2吨/米~2,也能取得一定的加固效果。

According to the experience both at home and abroad, it is shown that the vibrating water scouring method is used to encrypt the sand base and improve the liquefaction resistance of the sand base. The quality is good, the cost is low, and the effect is obvious. The method can be gradually popularized and used. Vibrating water method is applied to soft clay foundation. According to our country’s minority practice and reference to foreign experience, as long as the undrained shear strength of clay is not less than 2 ton / m ~ 2, it can also get some reinforcement effect.
