... Abstract The deformation modulus of rock mass is an important parameter for the design of underground structures and foundations. In this study, 3 new equations with statistical analyses were developed for estimation of rock mass deformation modulus using a database of 47 plate loads, 86...

... and reloading were observed. The linear character of the stress-strain response during reloading and unloading is more apparent at an increased confining pressure. Confining pressure reduces the difference of deformation modulus between unloading and reloading. The constitutive relationship for loading...

... element analyses for studies of the stress and displacement distribution around these types of projects are based on this parameter. The deformation modulus is, therefore, a cornerstone of many geomechanical analyses. Deformability is characterized by a modulus describing the relationship between...
