Reanalysis of Limit Creep Strain Determination of Geosynthetics through Accelerated Creep Tests

초록

For the better consideration of the long-term properties for geogrid, the installation damage index test, creep data results interpretation, chemical resistance test must be reviewed. But among them, creep deformation analysis is very important to predict the long-term stability which geogrids are used. In this study creep data interpretation is performed by using performance limit strain and isochoronous curve. From this procedure, we can obtain more accurate creep reduction factor at the aim design life. From this review and proposal of new procedure of installation damage test, more site-specific and more material-specific index test results are expected.
