摘　　要：通过建立早晚通风计算模型进行模拟计算,根据理论计算结果提出早晚通风节能模式。根据工程案例运行优化前后早晚通风模式的测试数据分析,建议取消晚通风模式,同时根据通风区段的长度,结合站间距进行组合,以减少参与模式的车站及风机的运行台数,并降低能耗。实践表明,早晚通风优化模式的节能效果明显,且能解决周边有敏感建筑车站的噪声问题。The simulation and calculation Is conducted on the basis of the calculation model of ventilation during the morning andevening time for subway tunnels. An optimized model is put forward. The test data collected before and after the model is optimized are operated by practical projects and the operation results show the evening ventilation model should be canceled, and the number of the operating tunnel fans should also be reduced to save energy. The optimized model is effective to save energy and can resolve the noise problem of those stations adjacent to sensitive buildings.
