Analytical reliability assessment of liquefaction potential based on cone penetration test results

Determination of site liquefaction potential and subsequent deterrent actioncan prevent signicant damage to structures. in this way, a probabilistic liquefactionassessment can develop potential exibility and risk management decisions. based onthe advantage of probabilistic assessment, considerable research has been carried out inthe past few years on liquefaction potential. in this research, the jointly distributedrandom variables method is used as an analytical method for probabilistic analysis andreliability assessment of liquefaction potential based on cone penetration test results. theselected stochastic parameters are corrected cpt tip resistance and the stress reductionfactor, which are modeled using a truncated normal probability density function and peakhorizontal earthquake acceleration ratio and magnitude, which are considered to have atruncated exponential probability density function. the depth of the water table and nescontent are regarded as constant parameters. the results are compared with those ofthe monte carlo simulation. comparison of the results and parametric analysis indicatesthe very good performance of the proposed approach in the assessment of reliability. asensitivity analysis shows that the moment magnitude is the most eective parameter insoil liquefaction potential.
