寒区隧道温度场分布反演及预测分析
|
摘要
为了研究多年冻土区隧道温度场的分布情况,文章以高海拔的青藏铁路风火山隧道为背景,利用有限元软件,考虑当地气温随时间变化等影响因素,对该寒区隧道温度场分布进行反演,将计算结果与现场实测数据进行比较,两者结果基本一致,说明利用该数值分析方法进行反演,能够得到可靠的计算结果。同时利用该模型对某寒区隧道断面的围岩温度场分布情况进行了预测,得到了隧道围岩受洞内气温的影响深度,可为类似多年冻土区隧道建设及相关领域的研究提供借鉴。
In order to study the tunnel surround rock temperature field in cold region, the numerical simulation model is established, considering the influence factors of temperature change based on the Huofengshan tunnel located in the Qinghai-Tibet plateau. The tunnel surround rock temperature field is inversed and the result of numerical simulation is compared with the field test data. Two results are basically identical to prove that the numerical simulation in the paper is reliable. Then,for a tunnel in cold region,the tunnel surround rock temperature field is predicted by the method, obtaining the affected depth of surrounding rock by the temperature in tunnel. It can provide reference for related research of tunnels in permafrost regions.
