The invention discloses a leveling hydraulic control system and an aerial work platform. The leveling hydraulic control system comprises a main oil way; the leveling oil way comprises a first leveling oil cylinder, a second leveling oil cylinder, a first balance valve and a second balance valve, and a rodless cavity of the first leveling oil cylinder and a rodless cavity of the second leveling oil cylinder are both communicated with the first oil port of the main oil way; a rod cavity of the first leveling oil cylinder and a rod cavity of the second leveling oil cylinder are both communicated with a second oil port of the main oil way, an oil inlet of the first balance valve is communicated with a rodless cavity of the second leveling oil cylinder, an oil outlet of the first balance valve is communicated with a first oil port of the main oil way, and an oil inlet of the second balance valve is communicated with the rod cavity of the second leveling oil cylinder. An oil outlet of the second balance valve is communicated with a second oil port of the main oil way; and the pressure supplementing oil way is used for supplementing hydraulic oil into the leveling oil way, so that the pressure value in the leveling oil way is kept at a preset pressure value.
