The invention discloses a method for optimizing the laying mode of a cable at two ends of a jacking pipe. The method comprises: step one, a jacking pipe is built based on a pipe-jacking construction technology; step two, a weldable cable protection tube with certain flexibility is added inside the jacking pipe and the cable protection tube is fixed by using plain concrete inside the jacking pipe at an interval of 5 to 10 meters; step three, the two end portions of the jacking pipe are blocked by concrete; step four, cable protection tubes with reinforced concrete protection are laid at the twosides of the jacking pipe obliquely and upwardly at a laying distance to the ground of 1 to 2 meters, and cable observation wells are constructed at the same position, wherein the cable observation wells are arranged above the two sides of the jacking pipe; and step five, a cable is laid in the laid cable protection tubes.
