摘　　要：利用AHP理论定量地分析了土层指标层对软基处理工艺层的影响,得到了土性指标层各因素对工艺选取影响程度的排序。对前湾软基区土性指标相关距离的变化情况进行了分析,通过与AHP分析得到的结论进行对比,得到了在该软基区域选择处理工艺时应重点考虑的土性指标。对不同处理工艺下的土性指标的变化进行统计分析,并建立了处理工艺评价指数,最终实现通过工艺评价指数来确定合适的处理工艺。In this paper, AHP theory is used in deciding treatment method on soft foundation in Qingdao Qianwan and a hierarchy model has been established. The relative weightiness of the GP level to the optimal method level has been calculated and the sequence of factors in GP level can be obtained from relative weightiness. The correlation distances of GPs have also been discussed and two sequences of GPs can be obtained from the analyses of GPs'correlation distance. Comparing three sequences, the important GPs which have great influence on choosing treatment method can be found. The data of GPs in nineteen ground improvement cases have also been counted. With the statistical analysis of important GPs,the estimation index of treatment methods can be established. Finally using the estimation index of treatment methods, an optimal method can be decided.
