Analysis on the Discrimination Method of Seismic Liquefaction
Jiang Chun Hu, Hong Fang Wang, Chen Li · Applied Mechanics and Materials · 2013
Seismic liquefaction is a major geological hazard of earthquakes. In the paper, the earthquake liquefaction of subway engineering in GUANGZHOU is calculated based on the standard penetration test method according to the rules of code for seismic design of buildings, specifications of earthquake resistant design for highway engineering, code for water resources and hydropower engineering geological investigation as well as the railway engineering anti-earthquake design specification. It is concluded that different code have very different result on sand liquefaction discrimination. And the data selection is a key factor when we discriminate sand liquefaction. The shortage of codes is evaluating the site liquefaction according to the data of points. The conclusions have positive role for engineering seismic liquefaction discrimination and the seismic liquefaction mechanism research.
