- Abstract:
- Yakaze landslide locating on the upper reaches of Dadu river is an ancient accumulation landslide that has bedding sided at initial stage. Its revival and deformation mechanism is closely related to surface water infiltration, heap loading on the rear and river erosion. Through GPS monitoring and field in vestigate of the landslide show that the deformation is synchronous, consistent and unequal obviously, the biggest displacement has occurred in front edge of the landslide with an annual displacement of 1.5 m/a, the rear of 0.25 m/a, its deformation shows the characteristics of a long term creep-sliding. There are many vertical, horizontal and shearing pressure crack development, which partly disintegrated landslide and resulted in whole undermining of landslide. Based on the above results we draw a conclusion that a high-speed sliding is unlikely in the future.
