liquefaction resistance of sand-silt mixtures using laboratory based shear wave velocity
laboratory data, which relate the liquefaction resistance of firoozkooh sand and non-plastic silt mixtures to shear wave velocity are presented and compared to liquefaction criteria derived from seismic field measurements by andrus and stokoe [1]. in the work described herein, cyclic triaxial and resonant column tests were conducted on specimens of clean sand and sand-silt mixtures with silt co...
متن کاملsoil liquefaction assessment of earthquake using the shear wave velocity (a case study in ardabil city)
1. introduction as the pressure of porous water increases in sand soils and saturated loose layers during an earthquake, the soil tendency to reduce its own volume leads to a decrease in the soil’s multifaceted tension. this way, the shear strength of the soil strongly decreases and comes close to zero. this phenomenon is called liquefaction. soil liquefaction is the cause of much destruction o...
متن کاملShear-Wave Velocity–Based Probabilistic and Deterministic Assessment of Seismic Soil Liquefaction Potential
Shear-wave velocity (Vs) offers a means to determine the seismic resistance of soil to liquefaction by a fundamental soil property. This paper presents the results of an 11-year international project to gather new Vs site data and develop probabilistic correlations for seismic soil liquefaction occurrence. Toward that objective, shear-wave velocity test sites were identified, and measurements m...
متن کاملGlobal Shear Wave Velocity Database for Probabilistic Assessment of the Initiation of Seismic-Soil Liquefaction
Engineering practitioners commonly use penetration-based methods (SPT & CPT) for assessment of seismic liquefaction triggering hazard. On the horizon, shear wave velocity (Vs) may offer engineers a third tool that is lower cost and provides more physically meaningful measurements. Development of the shear wave velocity liquefaction method has been hampered by a paucity of published velocity pro...
متن کاملA Workshop on Microzonation ©Interline Publishing, Bangalore Support Vector Machine for Evaluating Seismic Liquefaction Potential Using Shear Wave Velocity
The use of the shear wave velocity data as a field index for evaluating the liquefaction potential of sands is receiving increased attention because both shear wave velocity and liquefaction resistance are similarly influenced by many of the same factors such as void ratio, state of stress, stress history and geologic age. In this paper, the potential of support vector machines (SVM) based clas...
