介绍了我厂关键设备氧化铝沸腾焙烧炉罗茨鼓风机的功能，及自1997年11月投产以来先后发生四次事故的情况，重点分析了由于高压气体回流冲击而使同步齿轮与轴配合面产生相对滑移的可能，通过定量分析计算高压气体回流冲击时对主动转子产生冲量使其停止或反转的临界时间，同时提出了预防措施。

The instructive conclusion was: 1 under the vertical loading, the shear-lag effect was produced badly, more severer under concentrated loading than under uniform loading .2 the longitudinal bending deformation of the beam flange was true of the imitating plane assumption of deformation . 3 the width length ratio was confirmed as the first factor working on the shear-lag effect among all the geometric parameters;4 the shear-lag coefficient of simple-supported box-girder was severer than the continuous box-girder, the shear-lag effect in the inner supported section of continuous beam was much more severer, we need paying more attention for it in designing. 5 the non-liner characteristics of material deformation have littlie influence on shear-lag effect in BGCW. 6 the experiential calculating formulation and calculating diagram for the effective flange width was raised with the only factor of the width-span ratio., but the primary location of axis of bending moments should not be changed while calculating the inertial moment .

研究认为：1室内模型试验和空间有限元分析结果均表明波形钢腹板组合箱梁在竖向荷载作用下，翼板出现了典型的纵向应力剪滞效应。2在竖向荷载作用下，截面高度上各点纵向正应变分布认为可符合"拟平截面假定"，以此作为波形钢腹板组合箱梁抗弯计算的基本假定。3箱梁宽跨比是影响波形钢腹板组合箱梁翼板剪滞效应的主要因素。4连续波形钢腹板组合箱梁的翼板剪滞系数大于简支梁，且连续箱梁内支点截面翼板剪滞效应相当严重，对此需十分重视。5当混凝土翼板受力由弹性阶段进入弹塑性阶段时，材料的非线性特性对翼板的剪滞效应影响甚微。6提出了根据组合箱梁的宽跨比参数来计算翼板有效宽度比的经验公式和计算图表，但箱梁截面抗弯惯性矩的计算不应改变原先的截面中和轴位置。

The article finally through analyzing of the Zhejiang YiwuBinwang bridge temperature load, obtained the CFST arch bridge temperature stress rules with the temperature load which is including from top to bottom and from margin to core of arch-rib when the temperature value、 steel pipe wall thickness value and marking value of concrete change. The rule is that the axial force、 bending moment, as well as the shearing force elevates along with the change of temperature increases, so the control section stress which is linear relationship is. The article further proved the change of steel pipe wall thickness and marking value of concrete is not remarkable influence on temperature stress and internal force of arch ribs control section.

文章最后通过对浙江义乌宾王大桥温度荷载分析，得出了在由上至下和由周边向核心呈梯度变化的温度荷载作用下钢管混凝土拱桥结构应力随温度值、钢管壁厚值和混凝土标号值变化时的规律，即：轴力、弯矩以及剪力随着温度变化值增大而增大；钢管混凝土拱桥主拱肋的控制截面应力值亦随之增大，基本呈线性关系；并通过计算论证了拱肋各截面应力、内力值同钢管壁厚的变化、核心混凝土标号变化无关。
