*4.1. Conventional Liquefaction-Resistance Measures*

Generally, for seabed liquefiable foundation soils, it is imperative to lower the risks of liquefaction. Measures to reduce liquefaction damage can be summarized into three categories [16]: (i) reinforcement of seabed soil; (ii) improvement of pore water; and (iii) improvement of structures. In the design stages, the advantages and disadvantages of various remedial measures are compared, and the most suitable and economical method is selected. Sometimes, a combination of two or more countermeasures leads to better results.
