Evaluating soil liquefaction probability using CPT data

Thus,when the field testing liquefaction data from the various areas around the world are simultaneously employed to build a model to access the soil liquefaction,a extremely crucial issue appears that whether the different criterion can be matching.

According to the field testing liquefaction data of cone penetration test from 19 strong earthquakes around the world, the fuzzy uncertainties in construction of soil liquefaction discrimiant equation are analyzed.

A comprehensive physical model for liquefaction analysis has been discussed and applied to the analysis of ground liquefaction of Kunming.

The limitation of the ground liquefaction estimation under the code empirical formula is analyzed and the concept of applying the improved Internally Recurrent Net (IRN) model to estimate ground liquefaction is brought out.

The treatment of liquefied foundation in certain villa by compacted grouting method;

This paper introduces the general situation of the engineering and its geological structure characteristics,and probes into the problems of the deep cement mixing construction technology in the reinforcement treatment of the seriously liquefied foundation.

On the basis of field tests of the liquefied foundation reinforced with dry-vibro gravel piles of expressways,the theory of reinforcement with dry-vibro gravel piles and parameters of design and construction are discussed in this paper.

The feasibility and effectiveness of gravel compaction pile in treatment of highway liquefaction foundation are discussed from some aspects such as scheme design, construction control, effects measure and analysis, etc.

Rayleigh wave method is studied to appraise the improvement effects of the gravel piles for liquefaction foundation.

Application of dry-vibrated gravel pile in liquefiable foundation treatment;

Adopting deep bed stirring method to enhance liquefaction resistance of liquefiable foundation;
