复杂地质条件下，斜桩嵌岩钻孔过程中塌孔是影响施工效率的关键因素，采用单一的护孔方法往往难以奏效。文章通过施工实践，根据不同的地质条件，提出了泥浆护壁、压浆法处理、钢内护筒工艺等有针对性的护孔方法，可供类似工程借鉴。
複雜地質條件下，斜樁嵌巖鑽孔過程中塌孔是影響施工效率的關鍵因素，採用單一的護孔方法往往難以奏效。文章通過施工實踐，根據不同的地質條件，提齣瞭泥漿護壁、壓漿法處理、鋼內護筒工藝等有針對性的護孔方法，可供類似工程藉鑒。

The hole collapse in the rock socketed pile drilling process is the key factors affecting the efficiency of construction under complex geological conditions, using the single method of protecting hole is often difficult to work. Based on the construc-tion practice, we put forward some targeted methods of protecting hole according to different geological conditions, such as the mud supporting, grouting method, and steel tube technology, which can be used for reference to similar projects.
