Heat Exhaust Ventilation for Ultra long GIL Tunnel（超长GIL管廊排热通风研究）

The GIL chamber in the utility tunnel under Tanxinpei Road in Wuhan is an ultra long closed structure. Heat exhaust ventilation is the controlling problem in engineering design for the project, especially the heat transfer between the tunnel and the surrounding soil in the long term. A one dimensional model for the GIL chamber is established by using the IDA tunnel simulation software to analyze the short term and long term heat exhaust, respectively. The short term heat exhaust is analyzed for the typical climate of summer/winter/transitional seasons and the long term analysis is carried out under the seasonal changes in 1 year/ 10 years/ 30 years. The short term analysis results indicate that the slope of the utility tunnel and the temperature gradient lead to lower ventilation efficiency in certain areas. The long term analysis results show that the air temperature in the GIL chamber and the wall temperature rise most pronouncedly during the first 5-6 years of operation and remain stable for the remaining time within 30 years. It also is found that around 10%-40% of the heat is released to the surrounding soil. A three dimensional model of the GIL chamber is established using the fluid mechanics based program, OpenFOAM, for 3D simulation. The effects of cables and brackets on the temperature and velocity fields in the chamber are analyzed. The effect of non uniformity of velocity distribution and the stack effect on the temperature distribution in the GIL chamber are revealed. The results can provide some reference for the design and specification revision of heat exhaust ventilation for similar utility tunnels in the future.

城市“黑车”运输是我国公安交通管理部门重点打击对象。本文运用博弈论分析管理部门与“黑车”司机进行管制和“黑车”之间的降价竞争现象,结果表明,“黑车”市场存在的内在驱动力是有利可图;管理部门不应该仅仅从管制入手;理性的“黑车”司机在非法经营过程中也存在降价的驱动。本文最后在总结博弈分析结论基础上,分别从管理部门和“黑车”司机两个角度提出管理措施。结果表明,运用博弈论分析“黑车”问题具有理论和实际的意义。
