摘要:
为了研究列车活塞风对洞内温度场的影响，分别建立了二次衬砌、隔热层、一次衬砌及围岩的温度场计算模型，采用叠加原理、分离变量法和贝塞尔特征函数求得了列车活塞风影响下寒区隧道温度场的解析解．将解析解与现场实测结果进行比较，吻合较好．最后计算分析了不同行车速度和行车频率对洞内温度场及设防长度的影响．结果表明：在列车活塞风影响下，寒区隧道洞内温度变化明显，洞内气温出现正负交替的变化规律，不利于隧道内衬砌结构的防寒保温；列车行车速度和行车频率与单侧设防长度呈线性关系，该研究结论为寒区隧道的设计和防寒保温提供一定的理论支持．
Abstract:
In order to study the influence of train piston wind on the temperature field of the tunnel in cold region, the calculation models of temperature field for secondary lining, thermal insulation layer, primary lining and surrounding rock are established respectively. Analytic solutions of temperature field for the tunnel in cold region under the influence of the train piston wind are derived by using the superposition principle, the method of separation of variables and Bessel’s characteristic function. It can be found that the analytic solutions are in good agreement with the field measurement results. Finally, the impacts of different speed and frequency of train on the temperature field and the fortified length are analyzed. The results show that the temperature inside the tunnel varies obviously under the influence of train piston and is characterized by the alternatively positive and negative variations, which is not conducive to the cold insulation of the tunnel lining structure. The speed and frequency of train is linear with unilateral fortified length, This conclusion provides certain theoretical support for the design and cold insulation of tunnel in cold region.
