[0092] ρ1 is the influencing weight factor of the pipeline safety assessment index of the preset urban underground pipeline network renovation obtained from the underground pipeline network database.

[0093] ρ2 is the influencing weight factor of the pipeline leakage risk assessment index of the preset urban underground pipeline network renovation obtained from the underground pipeline network database.

[0094] The operating pressure borne by the urban underground pipeline network transformation pipeline is the influencing factor corresponding to the unit value of the urban underground pipeline network transformation pipeline leakage risk assessment index and the urban underground pipeline network transformation pipeline safety assessment index preset in the underground pipeline network database, which represents the numerical value of the influence of the urban underground pipeline network transformation pipeline leakage risk assessment index and the urban underground pipeline network transformation pipeline safety assessment index on the urban underground pipeline network transformation reliability assessment index. When used, the influencing factors corresponding to the urban underground pipeline network transformation pipeline leakage risk assessment index and the urban underground pipeline network transformation pipeline safety assessment index can be directly obtained from the underground pipeline network database. The corresponding relationship can be a preset mapping relationship. For example, the operating pressure borne by the urban underground pipeline network transformation pipeline and the unit value of the urban underground pipeline network transformation pipeline leakage risk assessment index and the urban underground pipeline network transformation pipeline safety assessment index preset in the underground pipeline network database and the corresponding influencing factors form a mapping set. The real-time urban underground pipeline network transformation pipeline leakage risk assessment index and the urban underground pipeline network transformation pipeline safety assessment index are input into the mapping set to obtain the influencing factors corresponding to the unit value of the urban underground pipeline network transformation pipeline leakage risk assessment index and the urban underground pipeline network transformation pipeline safety assessment index.
