| Abstract: | Liquefaction of low plasticity fine soils is observed during past earthquakes.It shall bear in mind at investigating seismic safety of engineering site that evaluation of liquefaction potential is carried out of the fine soils and the effective measure of liquefaction mitigation is taken.Based on recent earthquake discovery and research developments,the liquefaction criteria are suggested of the fine-grained soils to Chinese code for seismic design of buildings. |
