The present invention relates to a system and method of management and control of quasi-rectangular shield construction. The system comprises: a shield data acquisition device arranged in a tunnel and configured to collect the construction data in the process of shield tunneling machine construction; a plug-in subsystem configured to monitor the shield construction date in the tunnel in real time; a data exchange processor arranged in the tunnel configured to connect the data acquisition device and the plug-in subsystem through an exchange and transmit the construction data monitored by the plug-in subsystem to the data acquisition device; a data management center arranged on the ground and configured to connect the data exchange processor through the exchange to receive and display the construction data transmitted by the data exchange processor; a shield control PLC arranged in the tunnel and configured to control the shield tunneling machine which is connected with the data exchange processor through a bus. According to the invention, the safety and the reliability of an original control system of a shield tunneling machine are effectively ensured.
