The invention provides a method and a device for dynamic synchronous jacking compensation of bridge distortion and belongs to the technical field of bridge strengthening. A master control computer, a sub-pump, a substation and a height sensor work in coordination with each other, in combination with field monitoring data, parameters such as a pressure value, a rising height and a load are monitored by use of an electronic system in a multi-point numerical control manner, and therefore, multiple safety protection is ensured; an LCD (Liquid Crystal Display) screen is used for displaying the overall construction conditions.
