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.

To RPC, the fluidity was usually a key index, because it directly reflected the work-ability. The effect factors were complex, however, the quantity relation between the RPC fluidity and its effect factors could not be expressed with a uniform numeric formula. There was no effective method for this problem at present. In accordance, a numeric method which used for controlling the RPC fluidity was advanced. The neural network model based on genetic algorithm was introduced for a aptitude method consequently.
