一、引言 振动水冲法(简称振冲法)是利用一个能产生水平向振动的设备在高压水的帮助下使松砂地基振密或在软土地基中制造碎石桩,以提高地基强度、降低压缩性的一种地基加固方法。砂基用这一方法加密后,相对密度都在75％以上,承载力可达20～30吨/米~2,软基用 I. Introduction Vibrating water method (referred to as vibration method) is the use of a device that can produce horizontal vibration in high pressure water with the help of loose sand foundation or in soft soil to create gravel pile, in order to improve the strength of the foundation , To reduce the compressibility of a ground reinforcement method. Sand-based encryption using this method, the relative density of more than 75%, carrying capacity of up to 20 to 30 tons / m ~ 2, the use of soft
