摘要
以三峡永久船闸预应力锚索工程施工实践为例 ,详细分析锚索孔倾斜产生的地质条件、工艺因素 ,提出防止产生孔斜的措施 ,并详细介绍钻具保直组合系统。
The prestressed cable technique with high-resolution for the permanent ship gate of the Three Gorges Project is illustrated.The incling factors of hole such as geologic condition,drilling techniques etc.are analyzed,and a new technique is introduced to straight-keeping drill.
