Analysis of a Deep Shaft Excavation in Argillaceous Rock
The paper presents a coupled hydro-mechanical (HM) numerical analysis simulating an in situ test involving an excavation in argillaceous rocks. The test has been performed in the Meuse/Haute Marne laboratory of Eastern France, sited in a thick stratum of Callovo-Oxfordian mudstone. A specially developed numerical formulation and constitutive model have been used. The results of the analyses concerning displacements, pore pressures, damage and permeability variations are compared with observations. A satisfactory reproduction of the most relevant behaviour is achieved.
