<P>PROBLEM TO BE SOLVED: To provide a slope landscape construction method which is carried out in a short time and at a low cost, and forms a slope excellent in landscape on a front end side of a rock bed. Ž<P>SOLUTION: According to the slope landscape construction method, rock breakers 3 are inserted into uppermost portions of respective bore holes 6A to 6C, and positioned at almost the same height in the vertical direction. Then the rock bed 5 is broken with the rock breakers 3 at the positioned locations, and crushed and removed. Thus a front end upper surface 52 existing on the rock bed 5 before the crushing is removed from the rock bed 5 to expose a new front end upper surface 52, and the slope 53 is formed on a rear end side of the rock bed. Subsequently the rock breakers 3 are lowered and positioned at least once in a depth direction along the bore holes 6A to 6C, and the rock bed 5 is broken with the rock breakers 3 at the positioned locations whenever positioning is carried out, followed by crushing and removing the rock bed. In this manner the slope 53 is formed along the bore holes 6A to 6C, and thus the slope 53 is widened. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
