摘　　要：提出了1种层次分析法与模糊综合评价相结合的基础选型评价方法,以工程造价、设计条件、工期和施工条件为基础变量,采用层次分析法中的1~9标度法确定基础选型各项影响因素的权重系数,建立了评价基础选型的三层评价模型。运用该方法分析和评价琼州海峡跨海大桥6种已提出的深水基础形式,确定了最优的深水桥梁基础形式。A new approach for foundation selection was proposed combining analytic hierarchy process with fuzzy comprehensive evaluation. Three-level evaluation model of foundation selection was constructed based on basis variables, such as project cost, design condition, project duration and construction condition, and the weight coefficient of factors effected foundation selection was determined by using the 1 .9 scale law in the analytic hierarchy process. Taking the Qiongzhou strait cross sea bridge as the study object, based on the proposed six bridge foundation the comprehensive performance evaluation index system of foundation selection was established.
