Technical field
The utility model belongs to rock landslip field modelling technique field, more particularly to a kind of heavy showers induces rock landslip
Field model test apparatus.
Background technology
Landslide Hazards have：Sudden, species is more, multiple, seriousness the features such as.It is annual to occur landslide disaster energy
Account for the 70% of whole geological disasters, the principal element that wherein rainfall induces for landslide.The especially rock landslip of eastern Sichuan Basin,
Even more sudden strong, casualty rate is high, the infringement for having caused huge to people's life, property.In recent years, numerous scholars are slided to rock matter
The many-sides such as Disaster mechanism, failure mode and the governing measure on slope do excessive quantifier elimination, and achieve many achievements.Its
In, the firsthand data such as stress variation, deformation displacement inside slip mass is particularly important.If to rock landslip carry out stress,
The in-situ monitorings such as displacement, are difficult to predictability because the slip of rock landslip has, monitoring cycle can be caused uncontrollable, or even
Less than data；And landslide volume is huge, monitoring area extensively causes expense high.Therefore, numerous scholars, mechanism are tried using model
The method tested, can accomplish landslide cycle controllability, so that obtaining each item data more has reasonability.Slope model test,
Have the advantages that controllability is strong, mensuration means are flexible, the data obtained is comprehensive.Therefore slope model test is formed for Study of Landslides
Mechanism, failure mode, prophylactico-therapeutic measures are significant.At present, conventional rock landslip model test box, typically by test flume,
Loading system and various monitoring devices composition.Traditional rock landslip model casing has the following deficiency of some：
(1) traditional slope model test device, is indoor progress, using loose stone Mathematical Model of heaped-up slip mass, and
Gliding mass is not interfered globality preferably in practice, is so more or less disagreed with actual conditions.Therefore the data obtained
Do not conform to the actual conditions, it is representative not strong, it is impossible to meet test requirements document well.
(2) traditional slope model test device, gliding mass, slider bed, and slip band are according to the likelihood ratio, using analog material
Simulation is made, it is impossible to identical with actual condition.Equally cause the credibility of gained achievement not strong.
(3) rainfall is the main inducing that most rock landslips are produced.But traditional slope model test device, very
Rain factor is considered less.
The content of the invention
The purpose of this utility model is that providing a kind of heavy showers induces rock landslip field model test apparatus, it is intended to solve
Certainly traditional slope model test device exist the data obtained do not conform to the actual conditions, it is representative not strong, achievement is credible not strong to ask
Topic.
The utility model is achieved in that a kind of heavy showers induces rock landslip field model test apparatus, described strong

The heavy showers that the utility model is provided induces rock landslip field model test apparatus, chooses live bedrock landslide and enters
Row is artificial reconstructed, installs artificial rain system, lays a series of sensor, can accomplish that the data of rock landslip test are more closed
Reason, Thrust of Landslide, strain displacement are more directly perceived, and gained achievement is with more persuasion property.In the likelihood ratio, analog material are chosen：Pass
The slope model test method of system, reduces former Landslide Model using the likelihood ratio, certainly will so cause error；Especially in material
Selection on, because model is reduced using certain likelihood ratio, the likelihood ratio of the strength of materials should also reduce accordingly, but mould
The selection of section bar material is always the weak link of model test, notably directly regards test model material with raw material, so makes
Into error be also very important.The heavy showers that the utility model is provided induces rock landslip field model test apparatus, examination
Reconnaissance is tested directly in the rock slopes body prototype of given area to be carried out so that the scientific data of gained closer to true,
The puzzlement in terms of the suitable likelihood ratio cast material of selection is effectively prevent, gained achievement is more convincing.
During model foundation：(1) conventional model is used in loose stone Mathematical Model of heaped-up slip mass, work progress
This landslide will certainly be caused loose without close.And gliding mass is little affected by acutely disturbance, globality preferably in practice, so pass
System model is set up mode and can disagreed with actual conditions.Therefore the data obtained does not conform to the actual conditions, representativeness is not strong, it is impossible to very well
Ground meets test requirements document.(2) it is also task laying that conventional model, which sets up slip band, will also result in disturbance, and analog material choosing
The error taken, the scheme slip band that the utility model is provided uses the slip band that nature is generated.It is strong that the utility model is provided
Rainfall induces rock landslip field model test apparatus, and this just carries out experiment using natural slope, and work progress is to landslide
Disturbance is smaller, and slip band effectively overcomes above-mentioned error.
During simulated rainfall：The simple raining device provided using the utility model, by adjusting rainfall system control
Rainfall processed, can simulate influence degree of the different rainfall degree to landslide so that the data obtained is more full and accurate so that gained into
Fruit more fully, applicability it is stronger, can be broadly many peoples such as engineering staff, scholar service.
Conventional model is set up, and is that indoors artificial is built up, can only be carried out a scientific research, and dismounting, calcellation can be faced later
Situation, so cause conventional model utilization rate reduction, be also the waste in a kind of cost.The strong drop that the utility model is provided
Rain induces rock landslip field model test apparatus, and model structure size can be controlled, with flexibility is strong, easy construction, week
Phase is short, can reuse in different rainy seasons, the features such as can for a long time keeping, can carry out the scientific research project of different research contents,
And then greatly save experimentation cost.
