摘要

埋地管道在交通荷载等作用下会发生破坏，对区域内的经济和生活造成较大的影响。近年来废弃橡胶轮胎颗粒与土混合成轻质土逐渐被用于路基填料等领域。设计完成了冲击动载下橡胶?粉土轻质混合土中管道动力响应特性的模型试验，采用等体积置换法在地基土中掺入0%、10%、20%、30%的废轮胎颗粒，通过路基的表层沉降以及埋地管道的变形特性来研究轻质混合土作为路基填料的减振性能。试验结果表明，加入橡胶颗粒能有效减小路基表层沉降，当橡胶含量10%时，路基沉降减小最明显；埋地管道在冲击动载的作用下表现出“压扁”的形态特征，加入橡胶颗粒能明显减小埋地管道的应变及弯矩响应，当橡胶含量为20%和30%时，管道的应变和弯矩减小更为明显。

Abstract

The buried pipes will be destroyed under traffic loading

which will have a great influence on the economy and life in this area. In recent years

waste rubber tire particles mixed with soil are gradually used as backfill soil for subgrade and other fields. In this paper

the dynamic characteristics of pipe buried in rubber-silt lightweight mixtures under impact loading were investigated. In this study

10%

20% and 30% waste tire particles were added into the foundation soil by equal volume replacement method. The vibration absorption performance of light mixed soil as subgrade filler was studied through the surface settlement of subgrade and the deformation characteristics of buried pipeline. The results show that the addition of rubber particles to silty soil can effectively reduce the surface settlement of model soil. The settlement reduction is the most obvious with the 10% rubber content. The buried pipe shows a shape of "flattening" under impact loading. The addition of rubber particles can significantly reduce the strain and bending moment response of the buried pipe. When the rubber content is 20% and 30%

the strain and bending moment of the buried pipe decrease more obviously.
