SLOPE STABILIZING METHOD AND BEARING MEMBER USED THEREFOR

PROBLEM TO BE SOLVED: To provide a slope stabilizing method which does not make hard an operation for tightening a bearing plate when a large diameter anchor is used for increasing anchor installation intervals. SOLUTION: A bolt installation member 3 is attached to the upper section of the anchor 1, and three or more bolts 4 for imparting a bearing pressure are attached to the bolt installation member 3 in such a manner as to surround the anchor 1, generally vertical to a ground surface, and project from a ground when viewed from above. The bearing plate 5 is disposed on the ground in such a manner the each bolt 4 passes therethrough, and a nut 17 screwed with each bolt 4 is tightened to generate a bearing force in the bearing plate 5. Since the diameter of the bolt 4 for imparting a bearing force is small, an operation for tightening the nut 17 screwed with the bolt is not so difficult as in the case of an operation for tightening a large nut screwed with the thread section of a large diameter anchor with a large force.
