抗浮锚杆在玻璃工厂大型地坑中的应用探究

Discussion on Application of Anti-floating Anchor in Large Pit of Glass Factory

针对玻璃工厂联合车间大型地坑的抗浮问题,全长粘结型非预应力锚杆是有效的解决途径。锚固体长度、杆体截面积、群锚效应验算、抗裂验算均是抗浮锚杆设计时的重点内容。在探讨抗浮锚杆设计过程中有关技术问题的同时,对施工控制要点和试验检测要求提出建议。

In view of anti-floating problem of large-scale pit in the joint workshop of glass factory,full-length bonded non-prestressed anchor is an effective solution.Lengths of anchorage body,cross-sectional area of rod body,the checking calculation of group anchor effect and crack resistance are the key contents in the design of anti-floating anchor.This paper discusses the technical problems in the design process of anti-floating anchor,and puts forward some suggestions on the construction control points and test detection requirements.
