Study on design method of long-span corrugated steel arch culvert
In view of the imperfect design method of large-span corrugated steel plate arch culvert,combining with engi-neering design examples,this paper summarizes the characteristics of corrugated steel plate structure,analyzes the stress difference between corrugated steel plate arch culvert and reinforced concrete arch culvert,compares the standard calcula-tion method to the finite element model calculation method,and finally proposes that:as far as the high-filled corrugated steel plate arch culvert with 8-meter span being concerned,the stress is too small to be calculated by adopting standard calculation method.Therefore,it should apply the finite element analysis method,which takes soil-arch interaction into consideration.
