Description
Technical field
The present invention relates to a kind of liquefied foundation model test apparatus and method, belong to Geotechnical Engineering field.
Background technology
The stability of high slope of China is a practical situation comparing outstanding problem in Geotechnical Engineering at present.Opencut is high
Whether stability of slope directly influences safety and the economic benefit of opencut, but the mould in the open in ore deposit high slope practical study
Type test aspect, experts and scholars only to specific unit, single condition, lack and study in the range of universal Practical significance
Work；At present educational circles theory set up and actual application all lacks corresponding, science, there is actual installation guideline meaning
High slope model assay systems.
Vibration is a key factor of slope stability.Vibration can make slight slope soil property become loose, especially to water content
High fine sand, silt etc., liquefy because of vibrated, can cause a cubic metre of earth slope instability.The change of side slope active force is made
Become slope sliding.As at slope excavating, in side slope heap putting material, the vibration that piling, vehicle traveling, explosion, earthquake etc. cause, broken
It is broken original poised state.Meanwhile, also it is the inducement liquefied.
The principle of air spring: be filled with noble gas or gas mixture in airtight pressure cylinder, in making cavity
Several times of pressure superatmospheric or tens times, utilize the cross-sectional area of piston rod less than the cross-sectional area of piston thus produce
Pressure differential realizes the motion of piston rod.
Due to the fundamental difference in principle, air spring has a significant advantage than common spring: relative velocity slowly,
Dynamic force changes little (typically within 1:1.2), is easily controlled；Shortcoming is that relative volume does not has helical spring little, cost height,
Life-span is relatively short.
Air spring has working depth and can regulate at any time, and rigidity can be by the volume of auxiliary chamber and effective area
Being changed, spring system has the advantages such as almost unchanged performance.Air spring has nonlinear characteristic, and its rigidity is with load
Lotus and become, thus its natural frequency of vibration is almost unchanged under any load；Air spring can bear axial load and radial load, logical
The pressure overregulating rubber pneumatic bag compressed air inside can obtain different load-carrying properties.The rigidity of air spring, longitudinally height
Degree, rubber intracavity volume, load-carrying properties by the increase of the weight along with carrying, reduce generating period, soft flexible variety,
The soft succession of so power of being achieved that, effective control of vibration.Therefore consider to be applied to air spring vibration table model,
Thus it is applied to liquefaction test model.
Simplified model pilot system, uses better simply equipment and easy way simulation test truth more directly perceived.
Model is one of method most basic in scientific research, and it, in each door subject, has especially obtained widely in natural science
Application, and the simplification of model plays an important role at aspects such as Neo-Confucianism, engineerings, it can greatly simplify the place to object of study
Reason, particularly at the engineering problem of some complexity, it is possible to allow problem in the calculation simplifying problem on the premise of objective condition
Method, model etc., and then the most preferably solve in face of more complicated engineering problem (this section of Q5 and above five sections:
All should delete).
Generally, (Q6 should be herein: foundation liquefaction is the one of the main reasons of foundation eaerthquake damage, in recent years the whole world
The a lot of earthquakes occurred, cause substantial amounts of foundation liquefaction earthquake and occur, and cause huge Loss of Life and property.Natural
Under the conditions of) pressure of subsoil water maintains a poised state with the pressure of soil interlayer, keep between subsoil water and soil horizon connecing
Stablizing on mouth, can't invade soil layer above.But when subsoil water is vibrated, the mobile situation of subsoil water is by serious offense
The speed that unnecessary moisture can be discharged by sand.The bearing capacity of soil layer granule immediately can be given by water and replace, the internal meeting of Soil structure
Become the situation that can flow as liquid, cause a large amount of deformation of soil, eventually result in whole domain and lose carrying energy
Power (Q7 should be herein: under the effect of seismic dynamic loading, in the soil body, excess pore water pressure steeply rises, and effectively mean stress
Decreasing up to be zero, soil particle is in suspended state, and now sand just there occurs liquefaction.Due to the shearing strength of the soil body after liquefaction
All significantly reducing with modulus of shearing, result in that foundation bearing capacity is not enough, shake falls into excessive, until destroying unstability).Soil liquefaction occurs
Region easily cause above-ground structures inclination, sink, structural damage, the situation even collapsed.Currently, also there is no one
Simple and practical can observe and the assay device of above-ground structures sedimentation situation during Research Method for Foundation Liquefaction and method.
Summary of the invention
