Experiments for Buried Flexible Pipe Supported by Non-Uniform Bedding

摘要

There are many earthquakes and torrential rain in Japan. By thesereasons, the soil around the buried pipe is lost and the bed canbecome non-uniform. To clarify the behavior of buried pipe on thenon-uniform bedding, the model experiments and rosette analysiswere conducted. As a result, the concentration of stress and shearstress like a “twist” occurred at the buried pipe.
