Earthquake Drains
From GEOtechref
Seed, et. al., 2003, suggests that utilizing earthquake drains as a sole method for mitigating liquefaction hazards is unwise. This is due to the inherent difficulty in measuring the in-situ permeability of the potentially-liquefiable materials in order to size and space the columns effectively, but also because of the possible "plugging" of the drains, either during construction or over time, that may render the drains useless during the "few critical seconds of the earthquake." As such, it is recommended to use earthquake drains in conjunction with other mitigation methods. (Jbwisnie)
