【摘要】：通過(guò)鋼波紋管涵洞管周不同斷面的應(yīng)變值的有限元計(jì)算結(jié)果與現(xiàn)場(chǎng)實(shí)測(cè)結(jié)果進(jìn)行對(duì)比,采用有限元模型,對(duì)不同填土高度在公路-Ⅰ級(jí)荷載作用下的鋼波紋管涵洞受力變形進(jìn)行分析。結(jié)果表明:管頂0°～管周45°的壓應(yīng)變逐漸增大,而管周150°～180°逐漸減小,管周45°～120°波動(dòng)變化;波峰和波側(cè)都在管周120°出現(xiàn)最大應(yīng)變值,而波谷在管周90°出現(xiàn)最大應(yīng)變值;管周90°、120°應(yīng)作為重點(diǎn)位置觀測(cè)。
[Abstract]:The finite element model is adopted to compare the results of the finite element calculation of the strain values of different sections around the culvert of steel corrugated pipe with the field measured results.
