Hello,

This is the simple liquefaction demonstration equipment.

I made a liquefaction shaking table.

The motor used is 1800 rpm.

The sand box size is 25*30*25 (w*l*h)cm.

I use fine sand, particle size is around 0.1-0.5 mm.

The sand is saturated.

The water level is at the top of the sand.

Liquefaction only occurs in loose sand so I loose it before shaking.

When I start to shake it, the building model will sink into the sand.

The differnt type of foundation is no differrent in the result.

I use shallow foundation and pile foundation, both sink into the sand.

This is my researh at Civil Engineering, Chulalongkorn University, Thailand.
