摘要：

In an earlier work a deterministic model, FIRE-SPRINT A1, which predicts the conditions for fire spread in a tunnel, has been presented. The model, based on the concepts of non-linear dynamics, may be used to predict the conditions for spread from one vehicle to another in a tunnel fire. A few illustrative simulations were given. In this communication the results of further simulations are presented; in particular, bifurcation following has been conducted for the case of fire spread from one heavy goods vehicle to another in a rail tunnel. These demonstrate further how the model may be used to identify those geometrical and thermo-physical conditions which give rise to instability and a jump. In principle, such a model may be used as an aid to design and operation for a tunnel.
