Underground Deformation Measurement Using New Quartz Instruments
This work demonstrates the usage of two new quartz instruments, which are a tiltmeter and an extensometer that we developed lately to measure with high accuracy deformations of structures, volcanoes, tunnels, and ground surface. The stability of an underground quarry, near Paris in France was the subject of the study. The deformation of the quarry under different cases of loading during the pro...
متن کاملUrban underground development an overview of historical underground cities in Iran
The increasing rate of urbanization and rate of population growth over the 20th century has led to various problems such as traffic congestion, air pollution, and lack of open and green spaces that have affected the cities and their citizen's life. This condition has led to increasing demands for more land use, homes, and work places, more public transport and mass transit systems and modern in...
متن کاملDevelopment of a new creep testing equipment to obtain long-term deformation parameters of salt rocks
Creep phenomenon in rock engineering plays a key role in development of underground spaces as they must be stable enough for a long period of time. Current research involved designing and manufacturing of a new creep testing machine. The equipment is capable to perform simultaneous light-duty creep tests on more than one cylindrical rock samples at a very low cost.To evaluate the equipment’s pe...
متن کاملRadon-222 signatures of natural ventilation regimes in an underground quarry.
Radon-222 activity concentration has been monitored since 1999 in an underground limestone quarry located in Vincennes, near Paris, France. It is homogeneous in summer, with an average value of 1700 Bq m(-3), and varies from 730 to 1450 Bq m(-3) in winter, indicating natural ventilation with a rate ranging from 0.5 to 2.4 x 10(-6) s(-1) (0.04-0.22 day(-1)). This hypothesis is supported by measu...
