| Research Abstract |
Physical weathering of rock material induces loss of rigidity and deterioration of strength. This process was first reproduced in a newly developed testing device in which water-submergence, freezing, and heating were repeated. This test was able to reproduce the said rigidity loss and strength deterioration. Second, field studies were made in slope instability areas in both Japan and Pakistan where slope disasters have been significant. By using the knowledge thus collected, a methodology was developed by which the temporal progress of weathering and deterioration is traced and the mitigation of slope disaster is initiated at a critical time when the instability is imminent.
