摘要
对厦门地铁1号线屏蔽门制式的两站一区间进行了全尺寸的CFD仿真模拟,并对运营期间的隧道温度进行了长期监测,根据实测数据对仿真模型的边界条件进行了设定和完善。在关闭区间隧道排热系统的情况下,对运营初期和远期两种工况下的区间隧道进行了温度场模拟。通过与实测情况的校核优化模型,从而预测运营初期和远期不同工况下隧道内的温度情况,得出运营初期不开启隧道排热系统是可行的。运营远期壁温达到34℃时,需开启隧道排热系统,否则隧道区间将可能出现超温现象。
In order to establish a full-scale CFD simulation of one tunnel and two connected platform of Xiamen Metro Line 1 with which Platform Screen Doors System is adopted, a long-term monitoring of temperature concentration of tunnels was carried out. The boundary conditions of the simulation model were set and improved according to the measured data. In the case of closing the exhaust heat system of the tunnel, the temperature field is simulated under the initial operational period and long-term operation period. By optimizing the model with the measured data, the temperature in the tunnel can be predicted under different working conditions. The simulation results indicated that it is feasible to turn-off the heat-exhaust system during the initial operational period. After the long-term operating, tunnel wall temperature can reach 34℃, the OTE/UPE system should be opened, otherwise overheat will occurred in the tunnel.
