... Abstract In spite of a few reactors built inside rock caverns in the years 1950/70, the nuclear industry refuses to consider underground alternatives to surface plants. The first reactor accident occurred in a Swiss underground plant in 1969, without any health effect, as it was underground...

... Abstract With the advancement of science and technology, humans endeavoured to build massive caverns underground taking the advantage of physico-mechanical properties of the rockmass. The rockmass has inherent discontinuities in it whose properties vary greatly from the host rock aiding...

... Abstract 3D numerical modelling studies were carried out to study the behaviour of large twin caverns belonging to a hydroelectric project in Himalayan region. Various stages of extraction of the caverns were characterised by instrumentation studies. The cavern is oriented along the major...

...) in salt caverns. The constant axial stress rates range from 0.0001 to 0.1 MPa/s. The testing temperatures are maintained constant between 273and 373 Kelvin. The results indicate that the shear stress-strain curves monitored under various loading rates and temperatures show nonlinear relations...

... and pore pressure, thereby ensuring long-term safe LPG storage. Grouting was also conducted during the excavation of rock caverns so as to control the hydraulic conductivity of the rock mass appropriately. Pre-excavation grouting was conducted under high grouting pressure (about 4.2 MPa) in order...

... Abstract Japanese first underground LPG storage plants have been constructed by JOGMEC at two sites, Namikata and Kurashiki site. The principle of underground LPG storage employs groundwater pressure to contain LPG within an unlined rock cavern. Therefore, groundwater management during...
