The invention discloses a hydraulic control system and a garbage truck with the same. The hydraulic control system comprises an oil cylinder, a reversing valve, a double-hydraulic control hydraulic lock, a control valve and an energy accumulator, wherein the oil cylinder comprises a cylinder body and a piston rod, the piston rod is arranged in the cylinder body in a mode of being capable of movingin a reciprocating manner so as to divide the interior of the cylinder body into a rodless cavity and a rod cavity, and the piston rod is suitable for being connected with a tail door. According to the tail door hydraulic control system of the garbage truck provided by the embodiment, the control valve is provided so that the function of opening the tail door can be achieved by manually switchingthe control valve when the garbage truck fails, the situation that the tail door cannot be opened due to the fault of the garbage truck is avoided, in addition, due to the fact that the control valveonly needs to be switched under the condition of fault of the garbage truck, the control logic is simple, and the operation is convenient.
