Through analyzing Chinese seismicity situation

potential liquefaction risk and seismic mitigation techniques

the objective demand for liquefaction analytical methods is elucidated. Meanwhile

the existing liquefaction evaluating methods in Chinese seismic design codes are succinctly reviewed. Liquefaction investigation experience in the recent disastrous events is outlined and research ideas for modifying the provisions concerning on liquefaction in Chinese seismic design codes are proposed. By means of reviewing the seismic hazard assessment methods in China and analyzing key seismic observation areas and Quaternary deposit distribution

the necessity and urgency for developing liquefaction analytical methods are demonstrated. According to liquefaction investigation of 2003 Bachu earthquake in Xinjiang and 2008 great Wenchuan earthquake and comparing the liquefaction provisions in Chinese seismic design codes

ten research topics on improving and modifying the future liquefaction provisions in Chinese seismic design codes are proposed

including influence of liquefaction on the design response spectra; liquefaction evaluation methods of special soil categories; regional liquefaction evaluation norms; possibility evaluation techniques of site liquefaction; structural damage assessment based on PGD on liquefied sites; generating conditions for liquefaction-induced ground fissures; shear-wave-velocity based liquefaction evaluation methods; site liquefaction and risk assessment in seismic intensity VI; deep soil liquefaction evaluation methods and site liquefaction in-situ evaluation and detecting techniques.
