摘要
本文介绍杭州两座高层建筑物采用振冲碎石桩加固粉砂土地基的工程实例。结合有关现场测试成果，探讨了高层建筑振冲碎石桩地基设计计算、振冲碎石桩施工控制和加固效果评价等有关问题。为振冲碎石桩在同类地基中的推广应用提供一些成功经验。
In this paper,the case studies of two tall buildings built on silty sand improved by vibro- replacement stone column in Hangzhou are reported.The design and computation method for vibro- replacement stone column composite foundation are introduced.Based on field testing results,the construction techniques of vibro- replacement stone column and the appraisement of improvement effect are discussed.It is the first time that the vibro- replacement stone column method has been successfully applied to improve silty sand foundation of tall building in Hangzhou.
