To solve the problem of pile stabilization in the dock steep slope bare rock area, we carried out routine artificially flattened bed dumping, and the exploratory construction for the catheter frame pile stabilization process. We solved the technical problems such as pile stabilization temporary reinforcement, the construction study of catheter frame technology, and the positioning, ascension, solid, sinking of pile on site, according to different geologic conditions, and provided a referential basis for the pile stabilizing technology under the same kind geologic condition.
