摘要
为了使钢波纹管涵更好地发挥钢结构的优势,减少公路运营过程中的沉降、变形,以武安市莹玉公路为实例,通过创建波纹管模型,对运营车辆及填土对钢波纹管涵的受力影响进行分析,得出管周60°～120°应变值最大;同时对波纹管不同部位采取不同的回填方法,使填料与管涵的整体协调性良好,该方法为波纹管涵施工提供了理论指导。
In order to make the steel corrugated pipe culvert better take advantage of the steel structure and reduce the settlement and deformation in the normal process of highway operation,taking the Yingyu Highway in Wu an as an example,the force influence of operating vehicles and filling soil on steel corrugated pipe culvert was analyzed through the creation of corrugated pipe model.The results show that the maximum strain value of the pipe circumference is 60°-120°.Different backfill methods were adopted in different parts of the corrugated pipe to report the good overall coordination between the filler and the culvert,which can provide theoretical instruction for the construction of corrugated pipe culvert.
