一些因素对地下管线位移的影响

摘要

The impact of certain factors on displacement of underground pipeline were studied. The results show that the displacement of pipeline was related with the distance between pipeline and underground structure, pipeline material, the properties of substratum, buried depth of pipeline as well as the ratio of elasticity modulus between pipeline and surrounding soil to varying extent. Therefore, a reasonable design scheme should synthesize those factors above in the actual project.%研究了地下管线埋深、管材材料、管线下卧层土质、管线与地下结构间的距离以及管线与周围土层的相对刚度等因素对地下管线位移的影响。研究结果表明：以上各因素对地下管线位移均有不同程度的影响，实际工程中应该根据各影响因素综合分析后确定合理的设计与施工方案。
