The stress-strain behavior,and strength properties of reconstituted deep soils were studied to evaluate the effect of stress path on mechanical properties.

Numerical simulation of mine shaft excavation with full mine shaft drilling method based on deep soil and in-situ structural relation;

As undisturbed soil and remolded soil possess different structural features, they demonstrate different mechanical properties.

With the comparative analysis of triaxial tests of undisturbed and remolded soil samples, the influences of structure on the stress-strain shear moduli of soil samples at the initial, medium and later stages of the test have been discussed, and from the microscopic angle, its causes are analyzed qualitatively.

In laboratory,remolded soils are subjected to acid water immersion and tested for changes in their mineral compositions and shear strength after immersion with different durations.
