摘　　要：应用AHP＿Fuzzy多级模糊综合评判方法对天津市滨海新区工程地质适宜性进行了综合评价和分区。规定用建筑安全等级(Ⅰ、Ⅱ、Ⅲ)进行评价。安全等级为Ⅱ、Ⅲ级建筑通常采用天然地基和软土地基,对Ⅰ级建筑均需采用桩基。工程地质适宜性评价因子的选择以土性因子为主,权重用AHP层次分析法确定,单因素隶属度用剖分面积元的办法来确定。通过AHP＿Fuzzy两极模糊综合评判最后确定出的Ⅱ、Ⅲ及Ⅰ级建筑适宜性分区是符合实际的,具有较强的实用性。The suitability of engineering geology in castal new developed area in Tianjin city be synthetic assessed and districted by the method of AHP_Fuzzy in the paper. The paper provides the assessed standard is the building safety grade (Ⅰ,Ⅱ,Ⅲ) .The Ⅱ,Ⅲ grade building adopt natural and soft soil foundation,but Ⅰ is pile foundation.The assessed factor of engineering geology's suitability uses soil factor, weight is defined by AHP, single factor subjection degree is defined by dividing area.The building suitability defined in the last according to two_stage fuzzy synthetic assessment is consistent with practice,it has quite pleased practicability.
