- 摘要:
- 为了加强在役长输管道穿越隧道时地质灾害监测预警管理，预防或减缓隧道因地质条件发生变化给管道带来的安全风险，通过连续三期的隧址位移、隧道沉降、洞内应力和裂缝等方面的数据采集，并对数据进行处理分析、安全评估，结果表明隧道在监测期内未发生明显变形。但短期的监测不能客观真实地反映出隧道是否发生变形，为保证隧道在管道服役期内安全使用，应持续加强隧道动态变形监测，及时对隧道的安全状况进行评估，实现隧道安全预警管理。
In order to enhance the monitoring and early warning management on geological disasters in long-distance pipeline tunnel crossing, prevent or mitigate risks to pipeline due to geological condition change in tunnel, analyzed are data obtained in continuous three monitor stages of displacement, settlement, stress and fissuring and analysis results show that no tunnel displacement occur up to now. However, short-term monitoring results cannot reflect tunnel displacement change. Tunnel monitoring shall be continued and early warning management on tunnel geological disasters shall be strengthened constantly so as to ensure safe operation of the long-distance pipeline.
