Sand Liquefaction Through Volume Decrease Potential

open access: yesSoils and Foundations, 1976
ABSTRACT Cyclic triaxial shear tests were performed on granular materials with a variety of grain sizes and uniformity coefficients to determine the effect of grain composition on the liquefaction potential of cohesionless soils. In place of the conventional measure of relative-density as a density index the difference between the current and minimum

Evaluation model for soil liquefaction based on soil classification charts and its indices from cone penetration tests

open access: yesYantu gongcheng xuebao
The static cone penetration test (CPT) is an internationally used technique for potential evaluation of soil liquefaction in the world. The common method of CPT is based on the equivalent pure sand and only applicable to sand and low plastic fine-grained

Liquefaction Process of Sand During Cyclic Loading

open access: yesSoils and Foundations, 1972
ABSTRACT Both quick cyclic and slow cyclic shear tests are performed on saturated sand to investigate the process of liquefaction under the condition of constant mean principal stress. Special tests with varying amplitude of cyclic shear stress are also performed to estimate the change in excess pore water pressure during irregular cyclic loading ...

HISTORICAL OCCURENCE OF LIQUEFACTION IN ZAGREB AREA AND ESTIMATION OF REOCCURENCE IN CASE OF ANOTHER STRONG EARTHQUAKE

open access: yesRudarsko-geološko-naftni Zbornik, 2007
During the Great Zagreb's earthquake in 1880 consequences of the liquefaction have been detected at six sites in the vicinity of Zagreb as the occurrence of sand boils.

Compaction and Liquefaction of a Sandy Layer: Simulation of Shaking Table Experiments

open access: yesArchives of Civil Engineering, 2013
This paper presents numerical simulations of the behavior of a sandy layer subjected to a cyclic horizontal acceleration in shaking table tests, with a particular attention focused on the settlements of a dry sand layer, and on the liquefaction of ...

Prediction of Liquefaction in Sand Deposits during Earthquakes

open access: yesSoils and Foundations, 1976
A previously developed method for computing the progressive rise of pore pressures in saturated sands subjected to cyclic loading has been adjusted to fit data obtained from triaxial torsion tests. Also, the method has been incorporated into a computer code for the computation of pore pressures based on shear stresses obtained from an independent ...

Constitutive model for thixotropic fluid considering phase characteristics of liquefaction of saturated sand

open access: yesYantu gongcheng xuebao
Reasonable evaluation of the property evolution of saturated sand during liquefaction and the dynamic response under cyclic loading is the key to solve the problem of large deformation of liquefied sand.

Liquefaction resistance of MICP-treated calcareous sand with different particle size and gradation

open access: yesBiogeotechnics
Calcareous sand is a type of marine soil with the poor engineering performance and a high potential of liquefaction under seismic or wave action. To address this issue, microbially induced calcium carbonate precipitation (MICP), an eco-friendly bio ...
