ANALYSIS WHICH IS MATERIAL OF FOUNDATION AND BODY ABOUT PROGRESSIVE FAILURE OF RIVER LEVEE

Abstract

Small collapse at landside toe of levee may begin due to a rise of river water or rain, and then small collapses may be occurred in a chain reaction and reach big collapse finally. Such a progressive failure may be called internal erosion. Evaluation method for the failure of levee has not been established.

In this research, we experimented on the model test by something with different material about progressive failure.

As a result, we made it clear about the influential part of the progressive failure. It is found out difference in soil material has influence progressive failure of occurrence condition and speed.
