A 20 MN servo-controlled rock triaxial testing system with high temperature and high pressure developed by the authors is introduced.

Study on reinforced tailing sand by triaxial compression test;

The engineered treatment research of municipal solid waste (MSW) at a suburban building site was investigated in laboratory tests including sieve analyses, triaxial compression tests, simple shear tests, and isotropic consolidation tests to investigate the strength properties of municipal solid waste.

A series of laboratory triaxial compression tests on sand specimens reinforced with H-V orthogonal inclusions were carried out.

With the relationship between failure criterions and their relevant parameters determined through regress analysis,the results of tri-axial test on the rock mass,the mechanical parameters of the testing-rock were analyzed.

Aiming at some restricts and deficiencies of strain-equivalence hypothesis of Lemaitre and through introducing a statistical damage theory,a new statistical damage constitutive model was established based on the curves obtained from tri-axial tests,which could reflect mutual conversion for brittle and ductile properties of rock.

Tri-axial test is one of the most common soil tests, which brings out the soil constitute model parameters through the measurement of axial strain, radial strain and volume strain.
