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。
The research methods of extra load on apron pipeline network are summarized, the model and research status are simplified. Buried pipe load mainly includes static load and dynamic load, of which the static load mainly considers the filling load and the traffic load, and the dynamic load mainly considers the seismic response. In the past, the research on static load has paid little attention to the interaction between pipe and soil, and the study of seismic response usually does not take into account the inertial force of the pipe. Therefore, it is necessary to carry out the study on the random moving load of traffic which is closer to the actual situation. Appropriate pipe laying method, depth and soil compaction degree, can significantly reduce the horizontal and axial stress plane pipelines.
