Numerical thermo-hydro-mechanical modeling of compacted bentonite in China-mock-up test for deep geological disposal
چکیده انگلیسی

The China-mock-up test is to evaluate the performance of the compacted Gaomiaozi (GMZ) bentonite under coupled thermo-hydro-mechanical (THM) conditions in deep geological disposal. A numerical study of the test is conducted in this paper. The principal THM characteristics of the bentonite are presented at first. A THM model is then presented to tackle the complex coupling behavior of the bentonite. The model of Alonso-Gens is incorporated to reproduce the mechanical behavior of the bentonite under unsaturated conditions. With the proposed model, numerical simulations of the China-mock-up test are carried out by using the code of LAGAMINE. The time variations associated with the temperature, degree of saturation, suction and swelling pressure of the compacted bentonite are studied. The results suggest that the proposed model is able to reproduce the mechanical behavior of the bentonite, and to predict moisture motion under coupled THM conditions.
