摘要
为了确定小断面油气管道黄土隧道深浅埋分界深度及围岩松动荷载,结合郑州-西安高速铁路客运专线多条黄土隧道实测围岩松动荷载,采用理论分析和工程类比的方法,得到了具有意义的结论:(1)采用谢家然极大值法对小断面管道黄土隧道深浅埋划分结果合理,确定了小断面油气管道黄土隧道深浅埋分界范围:20.8~23.7 m,为(4.2~4.7)B(B为隧道开挖宽度);(2)根据既有大断面黄土隧道现场实测围岩荷载资料,对深浅埋荷载计算公式进行了相应修正,得到了适用于小断面油气管道黄土隧道的围岩松动荷载计算公式。
In order to determine the depth of shallow-deep burial and the loose load of surrounding rock of the loess in the small section of oil-gas pipeline tunnel,according to a number of test surrounding rock loose load of loess tunnel form Xi'an Zhengzhou high speed railway passenger dedicated line,the method of theoretical analysis and engineering analogy has been used.The results obtained are as follows:(1) The shallow-deep burial boundaries of the small section of oil and gas pipeline loess tunnel has determined by using the Xie Jiaxao maximum method.Shallow depth demarcation line of this type tunnel is 20.8~23.7m,for(4.2~4.7) B(B for the tunnel excavation width).(2) According to the surrounding rock load field test data of existing large section loess tunnel and the calculation formula of depth and buried load,the calculation formula of loose load of surrounding rock that is applicable to the small section oil and gas pipeline loess tunnel has been found.
