Abstract
In order to investigate the effect of improvement with bamboo mats on dredged fills, several tests were performed with different widthes (0.0B, 0.5B, 1.0B, 2.0B). The results indicate that the failure modes of the models without bamboo mats are close to local shear failure, and change to general shear failure as the width of a bamboo mat increases. A series of tests with four different widths (0.0B, 0.5B, 1.0B, 2.0B) were carried out on the models which have no desiccated surface layers, to find out the width that the general shear failure might occur. Finally, a series of tests with this width were performed on the models with three different desiccated surface layers (3cm, 5cm, 10cm). Throughout the tests, strength and deformation according to the thickness of desiccated surface layer was investigated.
