Description
Technical field
The present invention relates to Rock soil similar material physical model pour, maintenance, load test technical field, be more particularly to one
Kind of multi-functional large scale analog material physical model pours load test stand it is adaptable to various intensity Rock soil similar material physics
In model test whole process, the pouring of large scale rock-soil material model, maintenance, excavation, loading and monitoring.
Background technology
With the development of China's economic society, the quickening of urbanization process, increasing permanent resident population pours in limited
City space.Increase the contradiction nervous with land used for solving urban population, increasing city starts with the underground space and sends out
Exhibition underground traffic.The excavation of subterranean tunnel cavern will necessarily cause disturbance to protolith, causes surrouding rock stress redistribution, and then affects
The safety and stablization of surface buildingses.When particularly carrying out tunnel excavation in the relatively low broken formation of Surrounding Rock Strength, early stage is led to
Cross the physical mechanicses character that analog material physical experiments carry out weak surrounding rock during construction simulation, and then pass through model test
Counter push away construction parameter, this under complex geological condition it is ensured that the safety and stablization of engineering are significant.Subterranean tunnel
In construction process, different cavern excavation orders, different construction method, different impacts will necessarily be produced to country rock.
Find the problem that a kind of quick, economic, safe and efficient working procedure is industry more concern in recent years.With construction
Technological level and mechanical development, underground engineering tunnel excavated section is increasing, the construction that surface buildingses are caused
Disturbance is also increasing.In order to ensure the safety and stablization of engineering, all can strengthen to above ground structure and hole in work progress
The displacement deformation monitoring of room country rock.The frequency that in urban construction, large cross-section tunnel engineering occurs gets more and more, and that brings therewith is all
Many problems also become increasingly complex.Therefore, large cross-section tunnel excavation has become important and unavoidable in current underground engineering and has asked
Topic.
At present, during research weak broken formation tunnel excavation construction, the Main Means of coffer mechanics behavior mostly are numerical value
Analysis and model test, large scale, the construction method of large cross-section tunnel and adjoining rock stability Journal of Sex Research are the major subjects of the direction.
Although numerical analysis method has the advantages that simple and easy to do when studying complex construction problem, mathematical calculation model is past
Past quite different with Practical Project geological conditions.Therefore, almost all of Important Project, all can adopt the similar of certain likelihood ratio
Material model test carrys out construction simulation operating mode, and some engineerings even adopt 1:1 prototype test.Weak-fracture zone excavates
, because Surrounding Rock Strength is relatively low, easily there is the phenomenons such as collapse in cavern, country rock ruptures, therefore in this kind of Surrounding Rock Strength bar in cavern con struction
Under part, similarity material test becomes indispensable operation.
During carrying out similarity material test, choose the similar material mixture meeting Test in Situ mechanics parameter
It is the key of the method.This requires to carry out substantial amounts of proportioning test：Choose different material mixture ratios, make standard specimen, lead to
Cross uniaxial compressive test, direct shear test etc. to determine final proportioning.Simultaneously low-intensity large-scale model pouring, maintenance, excavation,
Supporting test-bed equipment is needed during loading etc..In recent years, lot of domestic and international scholar is also constantly advancing and is developing this
Class model test method and technology.Existing many scholars have carried out substantial amounts of work in terms of geomechanical model test, obtain
Many beneficial achievements and conclusion.
In place of existing testing equipment comes with some shortcomings at present：1. existing mould make standard specimen when, due to
Analog material low intensity, the demoulding that mostly occurs failure, test specimen is damaged, causes waste of material, affects test progress；2. model loads examination
Test stand pattern and fix it is impossible to the excavation under meeting different condition requires, existing most of test-beds cannot be realized " plus enclosing
The operating condition of test of pressure "；3. low-intensity analog material strain brick makes that mould is poorly efficient, consumptive material, success rate are low.According to the present invention many
Function large scale Rock soil similar material model test stand device, disclosure satisfy that large-scale model body pour, maintenance, excavation, plus
The requirement carrying and monitoring, by pre-buried monitoring element in model body, binding tests stand itself, during realizing to excavating
Surrouding rock stress, the real-time monitoring record of change in displacement rule.
