Description
Technical field
The utility model is related to a kind of Rock And Soil cutting creep instruments considering drying and watering cycle.It is followed in dry and wet suitable for testing
The mechanics parameter of soft rock or pan soil in ring environment.
Background technology
Drying and watering cycle is a kind of common natural operating mode, such as：Natural slope Rock And Soil is subjected to periodic rainfall and wind
Dry effect, reservoir stability Rock And Soil is subjected to periodic Reservoir Operation effect, so as to cause side slope inside Rock And Soil by the period
Property drying and watering cycle effect, drying and watering cycle effect promotes water and Rock And Soil and complicated physical-chemical reaction occurs, and finally leads
Cause gradually changing for rock mechanical characteristic.
The variation of the lower rock mechanical characteristic of drying and watering cycle effect is mainly shown as two aspects：1, Rock And Soil intensive parameter
(especially shear strength parameter) is continuously decreased with the increase of drying moistening cycle；2, Rock And Soil under stress conditions, with dry
Wet cyclic process gradually generates the deformation of creep.Under above-mentioned both sides collective effect, what the stability of side slope can be at any time pushes away
It moves and continuously decreases, therefore drying and watering cycle is a key factor for causing slope instability to destroy.
