Description
Technical field
The utility model is related to Geotechnical Engineering multifunction test systems technology field, and in particular to a kind of many work(of Geotechnical Engineering
The experiment slot device of energy pilot system.
Background technology
Geotechnical Engineering multifunction test system is to be applied to the experiment in the fields such as Geotechnical Engineering, underground engineering, mineral engineering
Research device, is the infrastructure and device systems of experimental study.Geotechnical Engineering multifunction test slot device is that Geotechnical Engineering is more
A part for functional breadboard system.
Rock And Soil is the product of nature, and its forming process, material composition and engineering characteristic are extremely complex, and
With stress, stress history, loading speed and drainage condition etc. difference and become more complicated.So, it is all kinds of in progress
Before project design and construction, it is necessary to carry out soil test and in-situ test to the Rock And Soil in place where engineering project,
To be fully understood by and grasp the physical and mechanical properties of Rock And Soil, so that provide must for the correct evaluation of place Geotechnical Engineering condition
The foundation wanted.With developing rapidly for China's modernization construction cause, new, higher want is proposed to Geotechnical Engineering measuring technology
Ask.Such as heavy_weight factory, high level, high-rise building, large-scale hydropower complex, railway, highway bridge and tunnel and civil building
Construction it is whether economical, rationally, largely depend on the engineering properties of ground.A geotechnical engineering problems are solved well,
It must be reconnoitred and be tested first, be tested with analyzing, and using the theory and method of soil mechanics, engineering geology etc., to each
Class civil engineering carries out systematic Study.Therefore, soil test is the previous work of Geotechnical Engineering planning and designing, be also ground with
Indispensable key link in basic engineering work.All engineering construction projects, including skyscraper, highway, machine
The construction in field, railway, tunnel etc., all has close relationship with their rely Rock And Soils of presence, largely depends on
Enough bearing capacities can be provided in Rock And Soil, be unlikely to depending on engineering structure by the settlement of foundation and difference more than permission
Deformation etc., and the parameter during foundation bearing capacity and foundation deformation are calculated is mainly what is determined by soil test, therefore, geotechnique
Experiment is indispensable for all kinds of Engineering Project Constructions.
Geotechnical Engineering multifunction test system is to study the important means of large-scale geotechnical engineering problems, has at home and abroad been obtained
Extensive use, and played important function in engineering scientific research, design and demonstration.In the world as the U.S., Britain, Germany, meaning are big
The developed countries such as profit, Japan, Norway have all successively carried out the Test And Research Work of Geotechnical Engineering multifunction test system, for stake
Native collective effect, the rock for accepting stable mechanism, efficiency of pile groups, large-scale mine roof rock, dam and the dam foundation of various stakes
The engineering problems such as body stabilization, huge underground cavity adjoining rock stability and supporting, have carried out fruitful research work, and have developed corresponding
Testing equipment；The country is such as Ground based studies institute of Chinese Research Institute for Building Sciences, Wuhan rock-soil mechanics research institute, Headquarters of the General Staff engineer section
Grind institute, Tsing-Hua University, University of Science ＆ Technology, Beijing, Hohai University, Railway Institutes Of Shijiazhuang, Beijing Inst. of Civil Engineering ＆ Arch, Tongji University,
The units such as Shandong University, have all successively carried out the research work of this respect, have developed scale and do not wait multifunction test system.
It is as follows the characteristics of test flume in all kinds multifunction test system：
1. big-and-middle-sized test flume typically uses reinforced concrete structure, entity steel construction；Small type groove be generally simply test pits,
Fiberglass steel-frame structure.
2. test flume is using embedding two kinds of forms above and below the ground.Reduced size test flume is typically directly made model casing and put
In ground；Larger test flume typically uses reinforced concrete structure, and bottom land absolute altitude is located at less than ± 0.000, the examination of underground buried
Check of foundation subsoil is easy to soil test to operate.The big-and-middle test flume of ground is placed in, there are two kinds of forms of reinforced concrete structure and steel construction, it is right
The rigidity of structure, intensity requirement are higher；The test flume major defect for being placed in ground is detrimental to soil test operation.
3. test flume planar dimension has rectangle and square two kinds, encloses two-dimensional space (such as：1.4m × 3m) or it is three-dimensional
Space is (such as：4.0m×5.0m；1.6m × 1.3m etc.).
4. test flume is generally single test groove, is only capable of carrying out a pilot project.
5. most of test flume (or experimental rig) size is fixed, and test space can not be adjusted.Large-scale experiment groove does smaller
During experiment, demarcation strip earth-retaining is typically used at random according to test requirements document, the test space required for being formed.Demarcation strip is generally entirety
Demarcation strip, is made using steel plate or poly (methyl methacrylate) plate.
6. the box-type rack installation of the development such as Shandong University Zhang Qiangyong realizes size adjustable, all cast steel boxlike structures of stand
Part is assembled, but cost is larger, and size adjusting needs to re-assembly stand.
7. mode is tamped in the transport of experiment earth material and layering：It is generally directly to be operated in test flume, layering is banketed
It is more difficult with test operation.The concrete test groove that Hohai University's Liu Hanlong is developed reserves door opening in side wall, is filled out in experiment
When native, the reinforced concrete gate of door opening piecemeal is closed；The box-type rack installation of the developments such as Shandong University Zhang Qiangyong can be reserved
One side wall, by the way of layering assembled box type component, to facilitate, earth material is transported and layering is tamped, but assembled box type component
Workload is larger.
8. experimental observation mode：The small-scale test groove for doing building enclosure using lucite can be observed directly, large-scale coagulation
Soil box or steel construction groove can not be realized to be observed in side, and the large-sized concrete groove of Liu Hanlong development is used to be set in wall diverse location
Put fixed emissive plastic glazing and solve this problem.But its structure is excessively complicated.
