- 摘要:
- 近两年，国内在高层建筑深基坑开挖的围护结构中，开始采用喷锚支护技术。该技术具有施工周期短，设备简单，工程造价低，边坡受力条件改善，加固效果显著等优点。本文概述了喷锚支护理论，并结合工程实践介绍喷锚支护设计和施工的若干问题，其中深基坑多层锚杆支护结构内力计算表具有合理、实用、简便的特点，易于设计人员接受。
In recent 2 years, the supporting technology of anchor spraying which is short in construction cycle, simple in equipments, low in engineering cost, effective in supporting and which improves the loading condition of side slopes, has been extensively used in supporting deep foundation pits for high buildings in our country. This paper introduces the principle of this supporting technology,and introduces some design and construction problems of the technology by combining the practice of the technology in construction. The calculation form for the internal force of the supporting structure with multi-story of anchor rods is reasonable, practical, simple and easily acceptable to designers.1995,4(4): 11-17 收稿日期：1994-10-18分类号：TU753参考文献：
