In　this　paper　a　practice　method　based　on　fuzzy　comprehensive　for　site　classification　is　established.　According　to　the　code　for　seismic　design　of　building　(GB50011-2010)　this　paper　chooses　two-parameter　indexes:　the　equivalent　shear　wave　velocity　and　overburden　thickness.　Firstly　in　order　to　get　the　universe　value　of　the　equivalent　shear　wave　velocity　and　overburden　thickness,　the　site　classification　standard　in　the　code　for　seismic　design　of　building　is　Equivalent　Transformed.　Then　according　to　the　assumption　that　the　membership　function　of　evaluation　factor　obeys　the　normal　distribution,　the　values　of　k　and　t　corresponding　to　the　two-parameter　indexes　are　obtained.　In　addition,　the　site　classification　is　gotten　the　fuzzy　comprehensive　assessment　by　weighted　algorithm　and　the　result　is　verified　by　the　Secondary　comprehensive　judgment　of　site　classification　based　on　the　range　groups　of　the　equivalent　shear　wave　velocity.　It　is　verified　that　the　method　is　feasible　and　effective　by　example　calculation　and　comparative　analysis.　The　evaluation　results　can　provide　a　theoretical　basis　for　site　classification.　©　2015　ejge.
