TRAVEL DISTANCE OF DEBRIS FLOWS TRIGGERED BY SLOPE FAILURES

摘要

The travel distance of debris flow is known as a function both of volume of failed rock mass and height difference as empirically shown by Scheidegger (1973) and Hsu (1975).The authors additionally plotted the travel distance of debris flows which took place in Japan and the Philippines in 2006 on the graph proposed by Scheidegger and Hsu. As the results, the authors obtained a band of data points similar to but somewhat different from the tendency given by Scheidegger and Hsu.
