First, we conduct the research on the mechanical mechanism of smoke control system to form a continuous water curtain and analysis the mechanical model of continuous water curtain and micro-unit; then simulate the continuous water curtain's shape of smoke prevention system by using Fluent software and the results are compared with the theoretical analysis; Finally, adopting the experimental verification of continuous water curtain shape and analyzing shape change of continuous water curtain in different water surface tension. Studies have shown that:1) the water curtain boundary track is curved, but the water curtain was similar to the shape of inverted trapezoid.2) under conditions of lowering the surface tension of water (test conditions), and continuous water curtain area growth rate with an average value is 0.26%, the width of growth rate with an average value is 17.32%, the length of the growth rate with an average value is -5.19%; Results indicates that the decrease of surface tension will cause the width of water curtain increase, the length is reduced ,but it has less effect to the area of water curtain
