Description
Technical field
The utility model relates to a kind of geomechanical model test device that uses in the energy, water conservancy, mine and traffic engineering field, specifically a kind of three-qimension geomechanics model exporiment bench frame apparatus.
Background technology
21 century is the century of Chinese engineering construction fast development, enters the new century, and the exploitation of heavy constructions such as water conservancy, water power, the energy, traffic has become the emphasis of China's economic construction.Along with the sustainable development of national economy and the enforcement of strategy to develop western regions, China has welcome the peak period that large-scale engineering is built, as large water conservancy hydroelectric engineerings such as Three Gorges, Long Tan, Xi Luodu, the south water to north; Large-scale energy project such as projects to divert gas and electricity from the western to the eastern regions; The large-scale underground space developments of large-scale traffic engineering and city such as Qinghai-Tibet Railway, Shanghai Rong's highway and subway engineering construction etc. are just being carried out in the whole nation with unprecedented speed and are being carried out.Meanwhile, oil and natural gas storage, nuclear waste disposal, CO2 store, rubbish the is buried and ultra-deep mining of oil, underground heat and mineral resources etc. also included the total development plan of country in.These large-scale construction project projects are on the one hand to accelerating the Chinese national economy development, uplift the people's living standard and keep social sustainable development will play great function, develop these heavy constructions simultaneously and will relate to the problem of many relevant ground strength failure mechanism, deformation instability condition and consolidation process in the face of a large amount of ground excavations.To these complicated problems, to go research by theoretical analysis, digital computer simulation method on the one hand, on the other hand, to solve by ground geomechanical model test means more.
Carry out geomechanical model test, corresponding model test stand device must be arranged, the present Research of at present relevant geomechanics model test stand device is as follows:
(1) 1994 year the 1st phase " Wuhan Water Conservancy and Electric Power Univ's journal " introduced two kinds of geomechanical model test devices, and a kind of is the plane stress test unit, and another kind is vertical Plane Strain Test device.The plane stress test unit mainly is welded into framed structure by the shaped steel steel plate.Vertical Plane Strain Test device is formed by the middle part fixed frame with along two forward and backward trave formula constraint steelframes of thickness direction, front and back two restrained beams are linked to be integral body with bolt with middle frame, guaranteed vertically do not producing displacement behind the model stand under load, thereby reached the requirement of plane strain.
This two covering device is applied in part underground workshop cavity group adjoining rock stability and supporting test, the subject matter of its existence is: moulded dimension is little, the model support fixed size, can't adjust according to experimental scale, device can not carry out three dimensional taest simultaneously.
(2) 2002 year the 5th phase " water conservancy journal " introduced a kind of model test frame, it mainly is made up of vertical pillars, closed steel construction ring beam, supporting steel frame, the size of this test stand is bigger, and the subject matter of existence is that the lateral deflection of test stand is big, and integral rigidity remains further to be strengthened.
(3) 2004 year the 3rd phase " rock mechanics and engineering journal " introduced the multi-functional simulation test device of a kind of Geotechnical Engineering, this test unit has two-way spinfunction, can be around 360 ° of model plane rotations, around 35 ° of model facade rotations, for the modelling of bad ground, the gravity stress of simulation rock soil mass and the influence of research side slope slope angle provide convenience.The subject matter that this device exists is the model stand fixed size, can not adjust according to trial stretch, and model test is small.
(4) 2003 year the 6th phase " modern tunneling technique " introduced a kind of frame beam type test-bed that is welded by shaped steel, and this stand can carry out the directrix plane strain-gauge test, but the distortion of stand lateral deflection is bigger, easily causes the change of test boundary condition.Simultaneously, the test unit fixed size can not be adjusted according to trial stretch.
(5) 2004 year the 21st phase " rock mechanics and engineering journal " introduced a kind of tunnel plane strain model test frame, and this stand is vertical layout, and the bench frame apparatus fixed size can not be adjusted according to trial stretch.
More above-mentioned a plurality of model test apparatus, can find their some common drawback:
(1) test unit many with the plane test-bed in the majority and stand fixed size, can not effectively adjust according to the model test scope.
(2) model test stand multi-purpose type steel is welded, and structure is plate-girder formula or frame girder structure, and under the lateral pressure effect, the distortion of stand lateral deflection is bigger usually, easily causes the change of test boundary condition.
Summary of the invention
The utility model is for overcoming above-mentioned the deficiencies in the prior art, provides a kind of easy accessibility, assembling diversity, size adjustable is whole and the three-qimension geomechanics model exporiment bench frame apparatus of easy operating.
The purpose of this utility model is to adopt following technical proposals to realize: a kind of three-qimension geomechanics model exporiment bench frame apparatus, connected to form by high-strength bolt by boxlike stand body and chassis, described boxlike stand body is connected by high-strength bolt with corner fittings by the boxlike cast steel member and combines.
Described boxlike cast steel member is made up of unit box body member and polynary box body member.
Described unit box body member is a hollow structure, is the square box body of front openings, is respectively equipped with the high-strength bolt connecting hole on four sides, is provided with the lead-in wire bleeder vent in the middle of the back side.
Described polynary box body member is integral by two or more at least unit box body component groups.
Described polynary box body member has binary box body member, ternary box body member, quaternary box body member and hexa-atomic box body member respectively.
Described corner fittings is the box body that the adjacent two sides of hollow are provided with opening, and its lap is provided with the high-strength bolt connecting hole.
Described chassis is spliced side by side by the shaped steel steel plate that has bolt slot.
The utility model is connected to form by high-strength bolt by boxlike stand body and chassis, and wherein boxlike stand body is connected by high-strength bolt with the corner fittings that is provided with around the corner by the boxlike cast steel member and combines.According to different needs, can form difform boxlike stand body by boxlike cast steel member and corner fittings.The boxlike cast steel member is made up of unit box body member and polynary box body member.Unit box body member is the square box body of the front openings of hollow, is respectively equipped with the high-strength bolt connecting hole on four sides, and center, the back side is provided with the lead-in wire bleeder vent of lead-in wire and the ventilative usefulness of material.Polynary box body member is integral by two or more at least unit box body component groups.Difference according to boxlike cast steel member size has the monobasic box body member that contains a box body, the binary box body member that contains two box bodys, the ternary box body member that contains three box bodys respectively, contain the quaternary box body member of four box bodys and contain the hexa-atomic box body member of six box bodys.Casing member adopts the 25Mn material to form in a molding monoblock cast of casting steel mill.The stand chassis is spliced side by side by the shaped steel steel plate that has bolt slot.Boxlike stand body and chassis can be fixed in desired bolt slot position by the high-strength coupling bolt in chassis, be formed combined type geomechanics model test stand device.
