Study of Radiant Interference based on Model of Electric Locomotive in Underground Tunnel
نویسنده
چکیده
This paper put forward a finite element method to study the radio transmission in tunnel electromagnetic environment. The author makes use of software simulation to study the rectangular tunnel model. When varying the electric parameters of tunnel wall, ceiling and floor, this may somewhat influence the propagation characteristics of electromagnetic wave.In order to study the interference properties of underground electric locomotive, this paper put forward a moment of method (MoM) model to analysis electromagnetic compatibility in roadway. The author makes use of FEKO software to simulate its timevarying and non-linear characteristics, the simulation results are in good agreement with experimental data. In the end it can be concludeed that this model has practical significance to estimate electromagnetic interference in coal mine.

Stability analysis of support systems using a coupled FEM-DFN model (Case study: a diversion tunnel at Lorestan dam site, Iran)
Various structural discontinuities, which form a discrete fracture network, play a significant role in the failure conditions and stability of the rock masses around underground excavations. Several continuum numerical methods have been used to study the stability of underground excavations in jointed rock masses but only few of them can take into account the influence of the pre-existing natur...
متن کاملConcurrent Locomotive Assignment and Freight Train Scheduling
The locomotive assignment and the freight train scheduling are important problems in railway transportation. Freight cars are coupled to form a freight rake. The freight rake becomes a train when a locomotive is coupled to it. The locomotive assignment problem assigns locomotives to a set of freight rakes in a way that, with minimum locomotive deadheading time, rake coupling delay and locomotiv...
متن کاملAssessment of Tunnel Excavation on Surface Settlement
The expansion of underground structures is important in urban areas with high population density. In most large cities in the world, urban development is spreading along the structures. These structures are generally located at shallow depth; therefore study of shallow tunnels in urban areas is critical for development. During the excavation of tunnels in urban areas, creating the asymmetric se...

The rock masses in a construction site of underground cavern are generally not continuous, due to the presence of discontinuities, such as bedding, joints, faults, and fractures. The performance of an underground cavern is principally ruled by the mechanical behaviors of the discontinuities in the vicinity of the cavern. During underground excavation, many surrounding rock failures have close r...
