Abstract
The large size geotextile sandbags filled with dredged soil are buried along the shore line to protect sea shore erosion. One of the geotextile sandbags at the Ooida coast in Miyazaki city was broken by high waves of the typhoon in 2014. Ministry of Land, Infrastructure, Transport and Tourism (MLIT) investigated the breakage mechanism of the geotextile sandbag. The reason of the breakage was that a concrete brock under the sandbag penetrated the geotextile. In this study, a series of the model tests were carried out to elucidate the breakage mechanism of geotextile sandbag by bending sandbags.
