A cellular automata-based simulation method of underground water bursting out and spreading along underground tunnel network system

A visualized simulation method based on cellular automata model is put forward, which is about water spreading along tunnels in an underground tunnel network system when an underground flood disaster happens. In the simulation model, the cellular automata model is applied to describe the flood spreading process in an underground tunnel network system, in which lattice cells are used to describe the tunnel network system, water cells are used to describe energy units of spreading water which is eradiated from break-points of rock aquiclude, each water cell contains such state parameters as velocity and quantity of contained water. During the simulating process, a great deal of information about flood spreading, destruction dynamics, degree of casualty and feasible measurements of adjustment and control can be obtained. In this method, time, space and behaviors of system are linked together, thus a more authentic and visualized simulation on flood spreading along tunnels is made.
