The invention discloses a distributed multi-point synchronous electro-hydraulic servo control system of a tunnel model test platform. The system is characterized in that the system comprises a controlmodule, an oil tank, a first variable pump, a second variable pump, a third variable pump, a first control valve, a second control valve, a third control valve, a fourth control valve, a fifth control valve and an execution module; and the system has the advantages that the opening and closing states of the first control valve, the second control valve, the third control valve, the fourth controlvalve and the fifth control valve are controlled through the valve bank control module, oil ways flowing out of an outlet of the first variable pump, an outlet of the second variable pump and an outlet of the third variable pump form a series-parallel structure, oil supply to corresponding proportional valve-controlled hydraulic cylinder groups can be achieved, joint oil supply can also be performed by controlling the opening and closing states of the fourth control valve and the fifth control valve, oil supply can be performed in any combined mode, flexible arrangement is achieved accordingto load needs, an energy saving effect can be achieved, and a mutual-standby oil way effect is also achieved.
