Description
Technical field
Landslide slip geotechnical testament apparatus field is the utility model is related to, in particular to a kind of landslide slip rheological test
Instrument.
Background technology
Slide strips soil classifiction property is to influence the key factor of landslide slip stability, design to Geological Engineering and is applied
Work all has important directive significance.The Main Means for obtaining landslide slip shearing strength property at present are to carry out landslide slip geotechnique to survey
Examination, a kind of the most frequently used method is exactly to carry out direct shear test.Conventional chambers direct shear apparatus is permitted due to the limitation of test apparatus size itself
Perhaps 1/10 of grain diameter no more than shear box size of maximum sample, often to be rejected during experiment particle diameter compared with
, there is dimensional effect and is disagreed with actual conditions in big particle.The specimen size of large direct shear test is big, the soil body is disturbed
It is dynamic small, using large-scale direct shear test can preferable reserve sample grading, so as to weaken dimensional effect closer to actually, at present
It is commonly used.
Landslide slip has rheological behavior, and its rheological behavior is not only relevant with suffered stress intensity, also by rings such as seepage flow
The influence of border factor.As one of most active factor of nature, the influence to landslide slip stability has particularly important water
Effect, osmosis can cause strength deterioration and the rheological effect enhancing of landslide slip.Such as reservoir landslide, due to storehouse water
The fluctuation of position, under periodicity osmosis and the effect of the long period of soaking of storehouse water, deteriorating effect occurs for the intensity of sliding soil within landslide zones

Power increases, so as to threaten the stability on landslide.Moreover, shown according to reservoir area landslide great mass of data, in the reservoir level rapid decrease phase
Between, the dynamic osmotic pressure of inclined slope aspect also increases in slope, and now Landslide Deformation speed also significantly increases.This explanation, osmotic pressure
Change can influence the strength and stability of sliding soil within landslide zones to some extent.
Investigate and find through inventor, existing slide strips soil large-scale rheological test instrument test data accuracy is relatively low, and can not
The lower landslide slip shearing strength deterioration of test constantly different osmotic power effect and rheological behavior.Therefore, study in osmotic pressure masterpiece
The deterioration of landslide slip shearing strength and rheological behavior under, a kind of landslide slip that can contemplate under the effect of different osmotic power of exploitation
Large-scale rheological test instrument, so as to obtain the Long-term Shear Strength parameter of landslide slip under seepage state.This is not only for landslide slip

The offers such as evil prediction more conform to the actual landslide slip intensive parameter of engineering.
In addition, generally, when seepage direction is identical with landslide slip detrusion direction, osmotic pressure is for slide strips
Native influence of shear strength is bigger, such as causes inclined slope aspect downward osmotic pressure increase during Drawdown of Reservoir Water Level, now comes down along slope
To detrusion also can substantially increase.Based on this realistic basis, when developing above-mentioned landslide slip shear rheology test instrument, will ooze
Stream direction is set to consistent with shear direction.
In view of this, it is accurate to design and manufacture a kind of measurement data, and landslide slip under different osmotic power can be measured and resisted
The large-scale landslide slip shear rheology test instrument for cutting Strength Changes is particularly important.
