【摘要】：综述了机坪输油管网附加外荷载的研究方法、简化模型及研究现状。埋地管道外荷载主要包括静力荷载和动力荷载,其中静力荷载主要考虑填土荷载和交通荷载,动力荷载主要考虑地震响应。以往对静力荷载的研究较少考虑管土之间的相互作用,对地震响应的研究通常也未考虑管体的惯性力作用,有必要开展更接近于实际状况的交通随机动荷载研究,采用合适的管道埋设方式、埋深及覆土夯实度,都能显著减小机坪管道的横向和轴向应力。
[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.
