Title:
LANDSLIDE PREVENTION STRUCTURE
Document Type and Number:
Japanese Patent JP3950790
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a landslide prevention structure, in which a plurality of resistors in the horizontal and vertical directions extensively over a section between the movable layer and immovable layer of a ground are disposed in the ground at regular intervals and by which resistance force is transmitted properly to the ground and a landslide is prevented while the landscape of a ground surface may not be changed.
SOLUTION: The approximately columnar resistors 10 are brought to the state, in which the resistors are extended to the movable layer 52 and the immovable layer 51 at the places of a sliding surface 60 on a ground 50, and arranged at regular intervals respectively in the inclined direction of the ground 50 and the crossing direction to the inclined direction while the resistors 10 directed in the horizontal direction are disposed at regular intervals among the resistors 10 in the vertical direction. A movement to the immovable layer 51 of the movable layer 52 is inhibited and the landslide can be prevented by increasing all of shear resistance at each position of the sliding surface 60 between the movable layer 52 and the immovable layer 51 by the resistors 10 in each direction supported to the immovable layer 51.
