Numerical Simulation of Liquefaction Deformation of Sand Layer around Bucket Foundations under Dynamic Loadings
The liquefaction deformation of sand layer around a bucket foundation is simulated under equivalent dynamic ice-induced loadings. A simplified numerical model is presented by taking the bucket-soil interaction into consideration. The development of vertical and horizontal liquefaction deformations are computed under equivalent dynamic ice-induced loadings. Firstly, the numerical model and resul...
متن کاملExperimental Study on the Responses of Bucket Foundations in Calcareous Sand under Vertical Dynamic Loading
Experiments to determine the vertical static bearing capacity are carried out first in laboratory which is taken as a reference for choosing the amplitudes of vertical dynamic loading. Then a series of experiments are carried out to study the influences of factors, such as the scales of bucket, the amplitude and frequency of loading, the density of soils etc.. According to the experimental resu...
متن کاملDynamic Responses of Bucket Foundations
Despite some studies on bearing capacity have been studied, the detail responses of the suction bucket foundations under dynamic loads have remained unknown [3]. The dynamic load condition is significant when suction buckets are used as the foundation of an offshore structure. Wave load, ice-induced or wind-induced load cause the foundation to be subjected to cyclic loads [4]. The dynamic load ...
متن کاملDimensionless Analysis of the Simulation of Bucket Foundations under Dynamic Load
Firstly, the main factors are obtained by use of dimensionless analysis. Secondly, the time scaling factors in centrifuge modeling of bucket foundations under dynamic load are analyzed based on dimensionless analysis and controlling equation. A simplified method for dealing with the conflict of scaling factors of the inertial and the percolation in sand foundation is presented. The presented me...

1257 In 1916, Baron Constantin von Economo, a Viennese neurologist, began to see patients with a new type of encephalitis that specifically attacked regions of the brain that regulate sleep and wakefulness. This disorder, which was eventually called encephalitis lethargica or von Economo’s sleeping sickness, swept through Europe and North America during the second decade of the twentieth centur...
