The invention provides a multi-point synchronous hydraulic jacking system. The multi-point synchronous hydraulic jacking system comprises a plurality of jacks, wherein a displacement sensor is arranged on each jack and used for detecting displacement of the jack; a solenoid valve is connected with the oil inlet end of each jack; the output terminals of the displacement sensors are all connected with slave control boxes; the output terminals of the slave control boxes are electrically connected with the solenoid valves; the oil inlet ends of the solenoid valves are connected with an oil pump through a main oil pipe; and a speed limit valve is arranged on the main oil pipe between the oil pump and the solenoid valves. Multiple points can be controlled by the slave control boxes to work synchronously, and part of the points can be operated to work synchronously; and some independent point can also be independently regulated, so that the practicability is high.
