- 摘要:
- 通过理论分析及查阅相关规范,针对西气东输二线隧道的特点,同时结合现场实际发生的塌方情况,提出了专门适用于油气输送管道隧道塌方的界定及分级标准,把隧道塌方按塌方量的大小分为小塌方、中塌方、大塌方三类,并给出三类塌方的标准处理方案。该标准处理方案应用于在建隧道塌方处理中,均取得良好的效果,管道安全顺利通过塌方段,实践证明,这种塌方处理方案可供今后其他类似工程参考。
Through theoretical analysis and consulting related standards, and investigating the tunnel characteristics of the Second West to East Gas Pipeline and the actual events of tunnel collapse, this paper brings forward the collapse definition and the classification standards which are specifically applicable to the tunnels of oil and gas pipelines. The tunnel collapses are divided into three types by the volume of tunnel collapse, including "small collapse, medium collapse and large collapse", and the standard treatment schemes of the three collapse types are given. These schemes have been applied in the tunnel collapse events of the Second West to East Gas Pipeline and have achieved good results. They can be used as reference for future similar projects.2012,2(2): 74-78 收稿日期:2011-1-8DOI:10.3969/j.issn.1001-2206.2012.02.021作者简介:胡文君(1980- ),男,湖南怀化人,工程师,2007年毕业于中国石油大学(华东),硕士,主要从事结构设计及研究工作.参考文献:
