不锈钢波纹板涵加劲肋受力数值分析与应用研究

摘要

With some stainless steel corrugate plate culvert with stiffening ribs as an example,this paper analyzes influences of distribution parameters of stiffening ribs on structural deformation,stress and pressure of backfill by means of finite element.The result of finite element analysis shows that ring stiffening ribs can improve flexural rigidity of stainless steel corrugated partial cross section,but shows small influences on pressure of backfill;stiffening ribs will cause increase of local stress of corrugated plates and should be taken into account in use.%以某带加劲肋的不锈钢波纹板涵洞结构为例，采用有限元来分析加劲肋布设参数对结构变形、应力以及回填土压力的影响。有限元分析结果表明：环向加劲肋能提高不锈钢波纹局部截面的抗弯刚度，但对回填土压力的影响较小；加劲肋会引起波纹板局部应力增大，使用中应予以重视。
