摘要

研究了平面地震波斜落作用下地下管道与弹性土的非定常耦合振动问题。导出了耦合自相似问题。得到了土壤外部问题的解析解。这个解决方案导致了管道和土壤之间相互作用力的理论表达式，而以前只有经验关系可用。管道在超声速和亚声速工况下的解表现出明显不同的特性，在进行抗震计算时应予以考虑。

Transient Oscillations of an Underground Pipeline and Soil at Inclined Fall of a Seismic Wave

The coupled unsteady vibrations of an underground pipeline and elastic soil caused by an inclined fall of a plane seismic wave are studied. The coupled self-similar problems are formulated. An analytical solution of the external problem for the soil is obtained. This solution leads to a theoretical expression for the force of interaction between the pipeline and the soil, for which only empirical relations were previously available. Solutions for pipeline in supersonic and subsonic cases demonstrate significantly different behavior, which should be taken into account during earthquake resistance calculations.
