The invention discloses an on-line stress monitoring multi-point synchronous pipeline lifting method, which relates to the technical field of pipeline repair, and comprises the following steps: S1, pipeline displacement calculation: analyzing and calculating the settlement displacement of a liquid inlet pipeline by combining a design drawing and field measurement; s2, a temporary limiting support is installed, specifically, the temporary limiting support is installed on the tank front steel structure frame layer; s3, a pipeline lifting bracket is installed, and a steel structure bearing frame is installed on the tank front steel structure frame layer to serve as a pipeline supporting and hanging frame fulcrum; s4, setting a pipeline lifting measure, S5, setting a pipeline lifting monitoring facility, calculating a stress concentration position through modeling, and setting a monitoring point at a position with relatively large strain; and S6, pipeline lifting confirmation. According to the online stress monitoring multi-point synchronous pipeline lifting method, the problem that on the premise that the strain is controllable, overall displacement is conducted on the system through the same pulling force at multiple points is solved, pipeline droop repairing can be met, cost and materials are saved, efficiency is improved, and the ecological environment is protected.
