用振动水冲法(简称振冲法),振冲碎石桩加固软弱地基,是一种比较好的加固方法,既经济又快,技术效果也好。我国在七十年代已陆续采用,在水电和建工部门用得较多,在铁路工程中虽有采用,但还不够普及。本文综合同类工程为例,介绍振冲碎石桩加固软土地基的设计、施工及经济技术效果。作者希望本文能对推广振冲碎石桩加固法尽微薄之力,并起抛砖引玉的作用。 The use of vibrating water (abbreviated as vibroflotation) to vibrate and gravel piles to reinforce the weak foundation is a relatively good reinforcement method. It is both economical and fast, and has good technical results. China has gradually adopted it in the 1970s, and it has been used more extensively in the hydropower and construction industries. Although it has been adopted in railway projects, it is still not popular enough. This article takes the same type of engineering as an example to introduce the design, construction and economic and technical effects of vibro-accomplished gravel piles for reinforcing soft ground. The author hopes that this article will do its utmost to promote the vibrating gravel pile reinforcement method, and will play a role in attracting jade.
