THE STRENGTH AND STABILITY ANALYSIS OF SUPER LARGE COOLING TOWERS WITH GAS FLUE

The strength and stability analysis of super large cooling tower with gas flue are calculated by finite element method． The research shows that stress concentration nearby the open hole is very distinct，and the safe factor of stability near holes is much less than the value without holes; Local stability of tower in the area of holes controls the design of such kind of cooling towers． The corresponding reinforcement schemes for cooling tower with gas flue are proposed lastly，and reinforcement effect of each scheme is compared for selecting the better one．
