PROBLEM TO BE SOLVED: To obtain the uniform bearing capacity irrespective of the presence/ absence of the degree of execution of slopes or boulder stones in a ground anchor method and a lock bolt method to stabilize the slopes, to miniaturize a bearing device of ground anchors, to green approximately the whole slopes, to reduce the execution cost due to weight reduction, and to reinforce and to prevent collapse of the slopes. SOLUTION: In a slope slip preventive method in which a slip on the slope (an arc slip, a compound slip, etc.), is resisted by ground anchors (a ground anchor, a lock bolt, etc.), the ground anchors are studded on the slope, and a slope independent bearing device 1 comprising a plurality of bearing piles 2 (excavated holes, steel bar anchors 5, reinforcing bars 7, grout 8) and bearing plates 3 is arranged at the position of execution of the ground anchors A, and the anchoring force of the ground anchors A is transmitted underground through the bearing plates 3 and the bearing piles 2 to execute the vegetation between the devices 1.
