| Abstract: | Mechanism of sand liquefaction is analyzed by using the principles of soil mechanics, soil dynamics, and groundwater dynamics. Relationship of variation among critical ultra|static pore water pressure of liquefaction and the duration of earthquake and embedded depth are proposed. The characteristics of liquefaction in Tangshan district are studied with the said theory and compared with the data. |
