【摘要】:綜述了機坪輸油管網附加外荷載的研究方法、簡化模型及研究現(xiàn)狀。埋地管道外荷載主要包括靜力荷載和動力荷載,其中靜力荷載主要考慮填土荷載和交通荷載,動力荷載主要考慮地震響應。以往對靜力荷載的研究較少考慮管土之間的相互作用,對地震響應的研究通常也未考慮管體的慣性力作用,有必要開展更接近于實際狀況的交通隨機動荷載研究,采用合適的管道埋設方式、埋深及覆土夯實度,都能顯著減小機坪管道的橫向和軸向應力。
[Abstract]:The research method, simplified model and research status of additional external load in airport oil pipeline network are reviewed in this paper. The external load of buried pipeline mainly includes static load and dynamic load, in which the static load mainly considers filling load and traffic load, and the dynamic load mainly considers seismic response. In the past, the interaction between pipe and soil was rarely considered in the study of static load, and the inertia force of pipe body was not usually taken into account in the study of seismic response. it is necessary to carry out the study of traffic dynamic load which is closer to the actual situation. The transverse and axial stress of airport pipeline can be significantly reduced by using suitable pipeline embedding mode, buried depth and compaction degree of overlying soil.
