The invention relates to a rail transit waterlogging dynamic simulation monitoring system and method based on digital twinning. At present, a waterlogging emergency disposal scheme cannot be formulated in time in rail transit operation management. The method comprises the following steps: creating three-dimensional models of each station and field section of rail transit, an earth surface runoff generation model, a pipe network confluence model, a river channel confluence model and an earth surface overflow model, and overlapping and coupling to form a waterlogging dynamic simulation digital twinborn body model; historical weather forecast rainfall meteorological data information is input into the model for dynamic simulation, and a historical simulation result is obtained; collecting and sensing equipment is arranged, and waterlogging state information is obtained in real time; weather forecast rainfall meteorological data information is obtained in real time; the information is input into the model, and a r
