摘要
就水平锚索孔的偏斜、导直机理和施工工艺作了分析和论述。采用水平孔导直理论和施工工艺在长江三峡永久船闸锚索孔施工中取得了良好的效果。
The deviation and pilot drilling mechanism and drilling technology of the horizontal cable bolt hole are analyzed and discussed in this paper The application of the horizontal pilot drilling theory and drilling technology to the cable bolt hole drilling for the perpetual ship gate at the Changjiang Three Gorges achieves good results
