随着我国经济建设的开展,对工程建设的投入不断增大,尤其是经济发展较快的沿海地区,正在兴建大量的基础设施和住宅楼、厂房等。在沿海地区,普遍存在有大量的软粘土,必须先处理好软土地基后方可兴建。因振冲碎石桩具有施工简便、承载力高、使用灵活缩短工期特点,近年来被广泛应用于软土地基的处理。采用振冲法加固软土地基构成桩土共同作用的复合地基,以提高地基承载力和减少基础沉降。
With the economic development in our country, the investment in engineering construction is constantly increasing. Especially in the coastal areas where economy develops rapidly, a large amount of infrastructure, residential buildings and factories are under construction. In the coastal areas, there is a widespread presence of large amounts of soft clay, which must be treated before the foundation of the soft soil can be constructed. Vibrating stone column has the advantages of simple construction, high bearing capacity and flexible and shortened construction period, and has been widely applied to the treatment of soft soil foundation in recent years. Vibration method is used to reinforce soft soil foundation to form a composite foundation with pile-soil interaction so as to improve foundation bearing capacity and reduce foundation settlement.
