In this paper, analysis was made on geological properties and artificial factors of silt and sand liquefaction in Wuhan City, and then the typical engineering section was chosen to conduct the liquefaction estimation and liquefaction index calculation. Lastly, conclusions were made on the hazard level of vibration and liquefaction and the main extents that need treatment. These information can be taken as reference for the engineering environment evaluation, quakeproof design and foundation construct and design.
