关于锚索造孔精度问题的探讨

Study on Precision of Cable Bolt Boring

摘要:

主要探讨水平锚孔造孔偏斜的机理及影响锚索造孔精度的原因，从理论上建立控偏、纠偏的数学模型以及从施工工艺及机具、钻进参数选择、工艺技术等方面探讨提高锚索造孔精度的问题。

Abstract:

Mechanism of inclination and causes of affecting precision of horizontal anchor hole are discussed. Mathematics model of rectify and control deviation is theoretically set up. How to increase precision in cable bolt boring is studied in construction technology and tools, selection to drilling parameters and technology.
