Geological Hazards analysis in Urban Tunneling by EPB Machine (Case study: Tehran subway line 7 tunnel)
Technological progress in tunneling has led to modern and efficient tunneling methods in vast underground spaces even under inappropriate geological conditions. Identification and access to appropriate and sufficient geological hazard data are key elements to successful construction of underground structures. Choice of the method, excavation machine, and prediction of suitable solutions to over...
متن کاملClimate forcing of geological and geomorphological hazards.
The 12 research papers and two summaries of conference discussion sessions contained in this Theme Issue build upon presentations and dialogue at the Third Johnston–Lavis Colloquium held at University College London in September 2009. The meeting brought together delegates from the UK, Europe and the USA to address the issue of climate forcing of geological and geomorphological hazards, with a ...
متن کاملStudy on Application of Electromagnetic Tomography Advanced Geological Prediction in Tunnel Construction
With the large-scale construction and rapid development of underground engineering, a large number of underground engineering construction, such as tunnel and subway emerged. The geological structure of the tunnel is complex and the roc is fragmented. The electromagnetic tomography is a new geophysical technique in the tunnel. This method has advantages such as high resolution, high reliability...
متن کاملDecompression sickness during construction of the Dartford Tunnel.
A clinical, radiological and statistical survey has been made of decompression sickness during the construction of the Dartford Tunnel. Over a period of two years, 1,200 men were employed on eight-hour shifts at pressures up to 28 pounds per square inch (p.s.i.). There were 689 cases of decompression sickness out of 122,000 compressions, an incidence of 0-56%. The majority of cases (94-9 %) wer...
متن کامل1 Ventilation System in Tunnel during Construction Works
Preface Construction works always involve danger and their environment is not always clean. In case of tunnelling works, especially in tunnels to be constructed with the drill and blast method, the problems on the safety and health such as the ones by dust and poison gas are serious subjects. This paper discusses the principle of ventilation system in tunnel during construction to provide good ...
