| 摘 要： | 涩北-西宁-兰州天然气输气管线约有200km铺设于黄土高原地区，在沟谷洪水、农田灌溉水的冲刷、潜蚀等作用下，出现管沟下沉塌陷、管堤冲毁、边坡滑塌等灾害，使管道悬空或露管，对输气管线的正常运营造成严重的危害和威胁．因而采取了塌陷回填、沟道防护、边坡支护等工程治理防治措施。

| Abstract: | There are about 200 km pipelines for oil transportation set in the loess plateau of Sebei-Xining-Lanzhou. Under the force of gully floods, eroding of farming water, the hazards occur in the forms of basement sink of pipelines, dam destruction by floods and slope sliding and they are very serious indeed. The water hazards have imperiled the safety of pipelines, so we have to take the countermeasures,in-cluding the backfill for pipeline basement, protection of gullies and slopes, and other preventive measures. |
