| It is important to grasp the transformation mechanism around the toe part of the landslide for evaluating the degree of hazard of collapse, but the measurement method which can grasp areal displacement for such part has not been established. Therefore, we have been developing a measurement method of the areal displacement using three-dimensional laser scanner (TLS).With TLS, we have made measurement of some slopes in Japan, and confirmed that TLS grasped the areal displacement on the slope where the landslide was being occurred. It leads to the idea that TLS is effective as a measurement method at the stage when the possible landslide area/level is uncertain.. |
