摘要
高地温条件对水工隧洞围岩稳定会产生较为显著的影响,温度场的存在使得围岩具有温度应力。因此,研究高地温条件下隧洞的温度场对围岩稳定具有重要意义。依托新疆某水利工程,采用现场试验的方法,对高地温引水隧洞围岩温度场进行监测分析,得出高地温隧洞围岩在不同工况下的温度场特性,得到温度场变化的主要影响因素,并提出复合衬砌的支护建议。研究结果可为相关高地温地下工程围岩温度场变化特征提供参考。
The high ground temperature condition will have a significant impact on the stability of surrounding rock of the hydraulic tunnel. The existence of the temperature field makes the surrounding rock have temperature stress. Therefore, it is of great significance to study the temperature field of the tunnel under the condition of high temperature for the stability of surrounding rock. In this paper, based on a water conservancy project in Xinjiang, the temperature field of the surrounding rock of the high temperature diversion tunnel is monitored and analyzed by the method of field test, and the temperature field characteristics of the surrounding rock of the high temperature tunnel under different working conditions are obtained. The main influencing factors of temperature field change are obtained, and the support suggestions of composite lining are put forward. The research results can provide a reference for the change characteristics of surrounding rock temperature field of related high temperature underground engineering.
