摘要
通过分析城市化带来的土地安全问题、环境安全问题、能源安全问题和交通事故引发的公共安全问题,详细论述了发展地下磁悬浮交通的动因。提出未来的城市交通和城际交通方式宜考虑发展地下磁悬浮交通,其中未来的城市客、货运交通宜发展地下中低速磁悬浮交通,而未来的城际交通宜发展成为绿色、低碳的地下高速磁悬浮交通。详细介绍了地下磁悬浮交通和地下物流系统的构造组成,重点介绍了地下磁悬浮系统具有节约土地、环境友好及高速大运量等优越性以及与该系统当前有关的试验研究成果,主要包括隧道的真空压力范围确定、截面设计、空气动力学试验模型、机械电力设备研究、生命支持系统研究以及建设成本估计等。
The causations for developing underground magnetic levitation are discussed by analyzing the problems of land security,environmental security,energy security and public safety problems caused by traffic accidents,which are brought by the rapid urbanization.The underground magnetic levitation system ought to be taken into account for the solution of in-city and intercity transportation problems in future.In this system,the in-city passenger transportation and freight transportation can be realized by low-medium speed underground magnetic levitation system,while the intercity transportation should be realized by the high-speed system,which is more green and more low-carbon.In the description of this new system,the compositions of underground magnetic levitation and underground logistic system are introduced in detail,the advantages in the underground magnetic levitation system,such as land conservation,environment-friendly,high speed and large capacity,are also presented.Apart from these,some important results of experimental researches are provided,which mainly include the determination of vacuum pressure,design of cross-section,aerodynamics test model,machines and electric power equipment research,life support system and construction cost assessment.
