| Research Abstract |
From the results of surface wave propagation test and model tests, it is clear that seepage water has large influence on long-term stability of embankment. Moreover, fine particle soil washed out and water path is formed by long-term seepage water. Therefore, even if deformation and settlement are not observed on the surface of embankment, earthquake resistance and stability may decrease. It is important to grasp the change of internal state of embankment.
The system of maintenance is proposed. In this system, the stability of embankment is evaluated by the grasp of internal state using surface propagation test in addition to visual inspection. By the management with such this system, the development of the priority of countermeasure and planning of long-term maintenance become easy.
