In case mud waves occur during reclamation, what are the possible solutions to rectify the situation?
Answer:
Answer:
- Option 1 – Complete Removal of All Disturbed Mud: To remove all disturbed mud once mud waves occur is the fastest way to treat the problem. After that, filling material is used for replacing the disturbed mud. However, this option is a rather expensive option because it involves dredging of all disturbed mud and replacement of large amount of fill.
- Option 2 – Accelerated consolidation of Disturbed Mud: This option involves placement of surcharging loads on top of mud waves, together with installation of band drains to accelerate the consolidation of disturbed mud. This method suffers from the drawback that sufficient long time is required for the consolidation process of mud.
- Option 3 – Partial Removal of Disturbed Mud: This option is a combination of the first two options in which the top weak layer of mud is removed while the lower mud is treated with surcharging with band drain installation.
