Liquefaction occurs when a soil deposit, typically a saturated fine-grained sand originally deposited in a loose condition, rearranges itself into a denser condition due to a disturbance such as an earthquake. A drastic example of this is the Turnagain district of Anchorage, AK, which suffered feet of settlement in the 1964 quake. Typical relationships I have seen reported between total and differential settlements are that differential is ½ to ¾ of total settlement. The Geotech for this project should be able to give more specific info. -----Original Message----- From: caidjs(--nospam--at)azstarnet.com [SMTP:caidjs(--nospam--at)azstarnet.com] Sent: Wednesday, October 14, 1998 1:50 PM To: seaint(--nospam--at)seaint.org Subject: Re: Piles >What means ".6" of liquefaction"?. I have never heard of that, and if it is in the literature it must be pretty obscure. What do they really mean? The settlements given are likely to mean overall site settlements...not "differential settlement" that the design must accommodate, which would be practically impossible.
