Analysis of sand soil liquefaction and reinforced measures;

Discussion on the Gan-Chen mode calculation method ofsand soil liquefaction depth;

Differentiation of sand soil liquefaction potentialbased on BP nerve network;

Interior stress change rule of sand soil liquefaction and criteria of engineering liquefaction;

To estimate the liquefaction possibility of the foundation under earthquake, a standard penetration test has been carried out.

The definitions of liquefaction and some basic concepts are discussed.

Artificial neural network model for prediction of seismic liquefaction of sand soil;

Aseismic reliability of traversing pipelines based on soil liquefaction analysis;

The tests made before and after the construction show that this technology has a good effect on reinforcing the foundation and eliminating the soil liquefaction.

Finally, by means of this model, the process and phenomena of the soil liquefaction is exp.

On the basis of constructional practice and testing data obtained at the experimental base of the key subjects of Xi an Highway University, this paper introduces the effects of strengthening liquefiable sandy soil by using vibrated gravel piles, its constructional measures, and further verifies its considerable efficiency in the strengthening of liquefiable sandy soil.
