Liquefaction and earthquake Liquefaction is an extraordinarly complex and potentially destructive phenomenon that can occur during a seismic event of significant intensity. The accelerations generated by a seismic event result in an increase in the neutral pressure of the interstitial water contained in saturated sandy soil.

Liquefaction resistance of soil with Liquiter

Geology

Liquefaction resistance of soil with Liquiter Simplified procedure for evaluating liquefaction resistance of soils Following disastrous earthquakes that occurred in Alaska and Niigata (Japan in 1964), Seed and Idris (1971) proposed a simplified methodology for assessing the resistance to liquefaction of soils. This methodology has been selected and improved over the years (e.g. Seed, 1979;…
