The modulus of elasticity of rock material is one of the most important rock properties used in designing civil and mining projects such as dam and tunnel constructions or mine layout design High quality core samples are needed to obtain this parameter using laboratory tests.
Jul 04 2020018332In many parts of the world dams hydroelectric power plants tunnels and highways have to be built in the regions where the weak rocks are dominant In the solution of the above mentioned geotechnical design problems the elasticity modulus is an important parameter to be found However it is quite difficult to find the elastic modulus E values of highly porous low strength rocks with.
Jun 21 2018018332Knowledge of the strength and elastic modulus of a reservoir rock is important for the optimisation of a particular geothermal resource The reservoir rock for many geothermal projects in the Upper Rhine Graben such as those at Soultz sous For234ts and Rittershoffen both France is porphyritic granite High fracture densities up to 30 fracturesm in this reservoir rock require that we.
The modulus of elasticity of intact rock E is an important rock property which is used as input parameter in the design stage of engineering projects such as slopes tunnel and mining excavations.
Mass elastic modulus using intact rock elastic modulus and lateral stress 3 3 Fahimifar carried out triaxial tests on a schist sample and found the increase curve of secant modulus at 50 of failure point for different angles and lateral stresses 4 Using wave propagation method through triaxial test cell Homand et al showed that.
Jan 22 2017018332Elastic modulus is a fundamental parameter in designing concrete structures In recent years building specifications have even required a specific elastic modulus of concrete to.
Mar 10 2012018332The modulus of elasticity of intact rock E i is an important rock property that is used as an input parameter in the design stage of engineering projects such as dams slopes foundations tunnel constructions and mining excavations However it is sometimes difficult to determine the modulus of elasticity in laboratory tests because high quality cores are required.
