沼泽地区管道的稳定方法

在我国西部地质、气候条件恶劣的沼泽地建设管道，其稳定方法是一个技术关键。在沼泽地的管道，除钢管自重，输送介质重量、回填土重量外，还有浮力、如果前三种力之和小于管道所受的浮力。管道将会上浮，相反，管道则会下沉，详细介绍了几种常用的管道稳定方法，并做了初步比较。指出，在沼泽地区管道的稳定不仅关系到管道的安全性，稳定性，同时也会影响到沼泽地区管道建设的投资。

Pipe Stabilizing Methods in Swampy Area

It is one of the key items to stabilize the pipes when building pipelines in the swampy areas of Westen China,where the geological and climate conditions are complicated. The pipeline in swamp is subject to the stresses of steel pipe weight,the weight of medium transported as well as buoyancy. If the sum of the first three forces is less than the buoyancy on pipe, the pipe intends to rise, otherwise,it will falls. Based on these two cases,several methods for pipe stabilization are described in detail,and comparisons between them made. It is pointed out that pipe stabilization in swamp not only determines the safe and stable operation of the pipeline system,but the costs for pipeline construction in this area.
