Abstract
Tn order to evaluate the applicability of a new band-shaped horizontal drain sandwitches by two types of geotextile on the seabed, a series of large scale laboratory consolidation tests and field tests were performed. Followings are the findings from the present study. Mud cake which may be accumulated between vertical and horizontal drain has almost no influence on consolidation efficiency. And also field tests using weight bags to set the horizontal drain on the seabed yield good results.
