- 摘要:
- 挤扩支盘桩是一种新的桩型,是在普通灌注桩的基础上,根据不同土层可以挤扩多节支盘,提高了桩的承载能力。本文从挤扩支盘桩的基本原理、作用机理、施工主要机具和设备、施工工艺流程、质量控制标准、工程应用实例及技术经济分析等方面进行介绍
The squeezing-spreading tray pile is a new type of pile. It is based on normal perfusion pile, greatly en-hanced the load carry capacity according to squeezing-spreading function in different soil stratum. The basic principle, function mechanism, main construction machine and tools, process flow, quality control standards, practical application and technical & economical analysis were introduced in this article.2002,3(3): 18-21 收稿日期：2002-1-6分类号：TU753作者简介：徐至钧,教授级高级工程师。现任北京恒富房地产公司总经理。通讯地址:北京宣武区马连道中里一区二号楼,邮编:100055参考文献：
