靖边—咸阳输油管道水工保护技术措施

The Hydrotechnological Protection Technology in Jingbian-Xianyang Oil Pipeline

针对靖边一咸阳输油管道线路工程湿陷性黄土敷设段的地形、地貌特点,通过分析湿陷性黄土遇水湿陷特性,针对管道施工期间自然地貌被扰动使原土体力学结构遭到破坏后,在外因水分作用下,造成管沟冲刷、沉陷、坍塌等不良现象,提出了管道在斜坡地段及崾岘地段敷设时应采取的水工保护技术措施。

Jingbian-Xianyang Oil Pipeline is 462. 2 km in total length,almost laid in the loess plateau. An overall analysis on the behavior of loess is made. To ensure the safety of oil pipeline laid in the loess plateau,especially for the oil or gas pipeline to be laid in the slop and steep hills,the hydrotechnological protection measures are proposed.
