摘要
针对大跨径钢波纹板拱涵设计方法不完善的问题,结合工程设计实例,总结钢波纹板结构的特点,分析钢波纹板拱涵与钢筋混凝土拱涵的受力区别,对比规范计算方法和有限元模型计算方法,提出对于跨径为8m的高填土钢波纹板拱涵,采用规范计算方法计算应力偏小,应采用考虑土拱相互作用的有限元分析方法.
Abstract
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.
