Description
Technical field
The present invention relates to the model test dress in geological disaster model test apparatus field, more particularly to a kind of collapse rock-fall
Put.
Background technology
Collapse rock-fall is one of common geological disaster in mountain area, and its occurrence frequency is high, and sudden strong, randomness is big, motion
Various informative, track is complicated, and difficulty of prevention and cure is big, often brings very big destruction to the building in the zone of influence, jeopardizes falling rocks influence
People life property safety in region, is the geologic hazard type of mountain area guard key.Study Initiated Mechanism, the fortune of collapse rock-fall
Dynamic characteristic is to carry out premise and the basis that collapse rock-fall is effectively prevented and treated.At present, RESEARCH ON THE COLLAPSE AND FALLING STONE method mainly includes theoretical point
Analysis, numerical simulation, field test and model test.Wherein, or theory analysis is simply on the basis of kinematic by some
It is assumed that after carry out theory deduction, or to the influence factor of falling rocks kinetic characteristic, it is considered to it is not comprehensive enough；Numerical simulation is set up one
The idealization of realistic simulation on fixed hypothesis basis, by all many limitations such as model parameter, correctness need into
One step is demonstrate,proved；Field test is limited by place, and experimental condition is single, and acquired results universality is limited, is not suitable for carrying out parameter
NULL, and time-consuming effort, both expensive, security are poor, complete independently relative difficulty；Tested under the conditions of model test
Condition is relatively controllable, is easy to setting shelving, slope angle, slope high condition, time-consuming short, spends few, comparatively safe, repeatability is strong,
Result of the test has preferable applicability to actual collapse rock-fall, and model test can combine the correlation that shake table shakes off stone over the ground in addition
Characteristic is studied, and is the important means for studying collapse rock-fall.
Good model test apparatus is that model test is smoothly carried out, test data possesses the premise of high confidence level, therefore
It is one of key factor of model test success or not to select correct model test apparatus.The shelving of side slope, slope are high, slope angle with
And earthquake is to influence the key factor of collapse rock-fall kinetic characteristic, and experimental rig function is more single at present, and slope angle can not connect
Continuous change, the high only limited adjustment in the single immutable, slope of shelving, domatic condition fixed single, geological process can not consider, and
Experimental rig is heavy, and not easy to install and dismounting, operability is poor.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of collapse rock-fall model test apparatus, can effectively solve slope
It is high single and the problems such as be difficult to accurately consider geological process that angle is difficult to consecutive variations, shelving and slope, approaches actual conditions, raising
Model test level.
The technical solution adopted for the present invention to solve the technical problems is as follows：
A kind of collapse rock-fall model test apparatus, by the slope of full angle spin canting 1 and adjustable full angle spin canting 1
Angle, high and shelving the auxiliary support mechanism composition in slope；Full angle spin canting 1 passes through gemel connection device by foreboard 10 and back plate 11
