The causes of shield tunnel defections could be divided into six branches: the segment dislocations, lining material deterioration and seepage. etc. Fault trees are also founded to illustrate each branch. 23 quantitative elements from the fault trees are selected to serve as the diagnosis indexes, all of which could be applied in engineering practice. By using the AHP method, a 3-level diagnosis index system is established. Afterwards, the procedure of setting up the quantitative judging criteria is given, as well as the relative index weight of index layer, by using the improved Analytic Hierarchy Process-multiplication scale method. At last, the values of corresponding parameters of membership functions are set, with the Cauchy distribution model.

将盾构隧道常见病害成因分为管片错位、衬砌材质劣化以及渗漏水等6个子系，对每个子系构建了病害故障树；从工程应用角度出发，从故障树中选取了23个可定量化因素作为评价指标，通过层次分析法建立了三层病害评价指标体系；对体系中单一评价指标的定量化分级方法进行简述，并给出所有指标的建议分级标准，采用改进的层次分析法－乘积标度法确定了各评判指标之间的相对权重；确定了基于Cauchy分布模型的隶属函数的关键参数。

The results showed that phosphating followed by coating acrylic acid can improve the adhesive strength. Increasing water temperature and the concentrations of cellulose nitrate in the buffer layer, decreasing the concentrations of R-2 resin and solvent can reduce the elongation.

结果表明，铝材表面经过磷化处理后，用丙烯酸金属涂料涂覆，可提高水转印后粘接性，转印时水温升高，过渡层配方中硝化棉增多，随R-2树脂减少，以及溶剂的减少都会使伸长率下降。
