Slope Stability Earth Anchor

Slope stability earth anchor:

Slope stability analysis of earth dam is very important to ascertain the stability of the structure. The stability of earth dam depends on its geometry, its components, materials, water pressure and the forces to which it is subjected. 

There is a slope stability earth anchor technique as one of the earth reinforcements to sustain the stability of the slope, which has been widely used for stabilizing cut slopes in Japan for the last thirty years. As ground anchors are anticipated to be deteriorated by geological environments such as ground water and natural disasters such as earthquake and typhoon, it is recommended to evaluate its performance by regular survey and tests. Moreover, it is believed that old-type anchors have a low protection performance against the corrosion on the surface of old-type anchors. Consequently, it is necessary to evaluate appropriately the damage of anchors as well as the stability of slope reinforced by deteriorated ground anchors. The performance of ground anchors is generally checked by soundness diagnosis, which is the visual check of anchor head, and lift-off tests, which is the loading test to measure a residual stress in anchor.

Many sliding strata exist in the Three Gorge Reservoir and the weathering products will landslide easily. Aiming at the accumulation formation of Triassic Padang Group in Beipei Landslide treatment project, this paper applied parameters reduction method to analysis the deformation mechanism and stability of the slope. Then the prevention and treatment measures were presented, aslo the reliability of the prevention projects of highway subgrade slope was analyzed. Completion of the Beipei Landslide Treatment Project for one year has proved that analysis and evaluation as well as treatment project are reasonable and effective.

Our percussion type earth anchor as a sope stabilization product is due to its load bearing plates which is spaced along the entire length of the anchor and screwed into the earth with minimal soil disturbance.
