摘要
川藏铁路桑珠岭隧道施工中出现了50~80℃的高地温,结合桑珠岭隧道高地温段施工遇到的困难及采取的工程措施,总结了高地温对隧道施工带来的主要影响,介绍了隧道施工中采用的降温、隔热、高温爆破及人员防护技术。实践表明,采用上述措施后隧道内环境温度降低了10~20℃,有效降低高温爆破安全风险,保障了施工人员健康安全。
In the construction of the Sangzhuling tunnel on Sichuan-Tibet Railway encountered 50 -80℃ high temperature. Combined with the difficulties and engineering measures in Sangzhuling tunnel, the main influences in the tunnel construction of high geothermal tunnel was summarized, temperature lowering technology, insulation technology, high temperature blasting technology and personnel protection technology were introduced. The practice shows that 10-20℃ was lowered in tunnel and the risk of high temperature blasting is effectively reduced, the health and safety of construction personnel are effectively guaranteed.
