Probabilistic pseudo-static analysis of pile foundations in liquefiable soils

Evaluation of seismic performance of pile-supported models in liquefiable soils

The seismic performance of four pile-supported models is studied for two conditions: (i) transient to full liquefaction condition, i.e. the phase when excess pore pressure gradually increases during the shaking; (ii) full liquefaction condition, i.e. defined as the state where the seismically induced excess pore pressure equalises to the overburden stress. The paper describes two complementary ...

Variables Characteristics Effects on Static and Pseudo-Static Reliability-Based Design of near Slope Shallow Foundations

Given the concept of reliability-based design (RBD) and the growing risk management trend in geotechnical engineering, proper understanding and quantification of uncertainties are very important. The complexity of methods and a large volume of calculations of probabilistic design methods are the most critical reasons for civil engineers not to be comfortable using these approaches. In this rese...

Dynamic Stiffness of Piles in Liquefiable Soils

Parameters Analysis of the Covering Soil of Tunnels Constructed In Liquefiable Soils

Earthquake and its catastrophic failures has been one of the disturbance worry of Civil Engineers. In geotechnical science, liquefaction is one of the most important phenomenons induced by earthquake. A change in pore water pressure follows a change in effective stress, and in a critical state in which pore water pressure equals the total stress in soil particles, soil strength is suddenly lost...
