| Abstract: | The paper takes as an example the project of trench-extension in bedding high rock slope at K174 ＋ 790 - ＋ 907 on the left side of Hujiaying station along Wuhan-Ankang railway line. It is explained in details the chosen protection construetion which is close to the existing line and under conditions of developed rock joints, abrupt mountains, and bedding slope, etc. The paper also generalizes the comprehensive application of protection measures like controlled explosion close to existing line, partition demolishment and dangerous rock disposal. Therefore it accumulates referential materials for similar projects in the aspects of construction organization, setting down protection measures etc. |
