| Abstract: | This paper introduces the geological condition of No.18 sluice gate in Xiajiang Hydro Project.As a part of the powerhouse’s longitudinal cofferdam used all the year,the right pier may become a sliding block toward the powerhouse pit because of the combination of soft intercalate layer and fracture in foundation rock,and the safety coefficient K′ against sliding could not meet the requirements in specification only when some treatment measures are applied,such as consolidation grouting,drainage,shotcrete-anchorage,prestressed anchorage cable,pile with anchors,etc. |

| Keywords: | foundation bed soft intercalated layer stability against sliding foundation treatment |
