Abstract

There are many small earth dams for irrigation called "TAMEIKE" in Japan, Most of them were constructed before modern soil engineering were established on the basis of empirical techniques. Earthquakes in the past gave much damage to these earth dams. This paper surveys damage of earthquake for those remaining on records again, and as for Nipponkai-Chubu Earthquake, detailed investigations such as in-situ test, laboratory test, analysis were made to clarify causes of the damage to earth dams. From the result of survey, the following matters were found; i.e., large damages occur at a high rate on earth dams whose foundation ground and embankment are consist of loose sand, and the major cause of the damage is liquefaction. When the embankment and the foundation ground are made of cohesive soil, the degree of damage is relatively small.

Consideration of Earthquake Damage to Earth Dam for Irrigation in Japan

St. Louis, Missouri

There are many small earth dams for irrigation called "TAMEIKE" in Japan, Most of them were constructed before modern soil engineering were established on the basis of empirical techniques. Earthquakes in the past gave much damage to these earth dams. This paper surveys damage of earthquake for those remaining on records again, and as for Nipponkai-Chubu Earthquake, detailed investigations such as in-situ test, laboratory test, analysis were made to clarify causes of the damage to earth dams. From the result of survey, the following matters were found; i.e., large damages occur at a high rate on earth dams whose foundation ground and embankment are consist of loose sand, and the major cause of the damage is liquefaction. When the embankment and the foundation ground are made of cohesive soil, the degree of damage is relatively small.
