Marine Stone Columns to Prevent Earthquake Induced Soil Liquefaction
Abstract With ports and other near shore structures expanding, and regions previously not considered prone to earthquakes being re-classified after recent earthquake events, ground improvement by stone columns is increasingly considered to improve loose or soft in situ soils. The Dry Bottom Feed Stone Column construction technique can be used under water if a double-lock stone delivery system is attached to the vibroprobe. The use of pneumatic stone transport from the barge into the vibroprobe receiver tank makes it possible to reach large water and treatment depths. Digital recording of all relevant operation parameters provides a very high level of quality assurance, including a diameter-over-depth profile for each stone column. An introduction to earthquake-resistant design of stone columns and guidelines for specifying Marine Stone Columns are given.
