地震波对乌鲁木齐河谷地下管线的影响
|
摘要
根据乌鲁木齐河谷的1~3级阶地和地层岩性,分析了在地震波作用下地基土层剧烈复杂振动对地下管线的影响,表明场地内地质构造、地形条件的特殊性加重了地震灾害。通过乌鲁木齐河谷的天然气钢结构管道地震应力计算,讨论了地震波对地下管道的应力作用,其大小主要由表层土体产生的变形或应变决定。提出了建设乌鲁木齐市河滩路地下管线公用隧道工程建议,这是保护地下管线的有效方案。
Based on the third terrace and the stratum lithology of Urumqi river valley,the article analyzes the influence on underground pipeline,which is from violent and complicated vibration of groundwork soil layer from seismic wave.It indicates that earthquake disaster is aggravated by particularity of geological structure and terrain condition.By calculating stress value of natural gas steel pipeline in Urumqi river valley,we discuss the stress action of seismic wave on underground pipeline,which depends on deformation and strain from surface soil.The article proposes that constructing public tunnel of underground pipeline on Hetan Road,in Urumqi city is an effective scheme to protect underground pipeline.
