Description
Technical field
The utility model belongs to the Geotechnical Engineering testing equipment.
Background technology
Geomechanical model testing technology is that the important means of the large-scale geotechnical engineering problems of research at home and abroad is used widely, and in engineering scientific research and design and demonstration, brought into play vital role, all successively carried out the experimental study work of geomechanics model in the world as developed countries such as the U.S., USSR (Union of Soviet Socialist Republics), Germany, Italy, Japan, Norway, stable at the large-scale mine roof rock, the dam dam body is stable with the rock mass of the dam foundation, large-scale surrounding rock of chamber is stable and engineering problem such as supporting has carried out fruitful research work, and has developed corresponding testing equipment.More domestic units have all successively carried out the research work of this respect, have developed the supporting model test equipment that scale does not wait.
For the underground works model experiment, the geometric similarity of its empirical model is than the technical indicator that is a key.The geometric similarity ratio is obtained too small, though can save experiment material, the layout of still too small model scale of construction meeting limiting sensor is compared with bigger model, the easier interference that is subjected to extraneous factor, thus influence experimental result.If it is excessive that the model geometric ratio of similitude obtains, then can increase the complicacy of model experiment itself, the analog material large usage quantity that experiment needs as large-scale model; When the big buried depth complex working condition of simulation, need the bigger counter force system of large-tonnage loading system and rigidity, thereby directly cause experimental system cost ground significantly to improve.Therefore, how the balance test relation of accuracy and experiment table economy as a result is the major issue that the R﹠D work of model experiment platform need be considered.Along with the scale of Geotechnical Engineering is increasing, the engineering problem that occurs is complicated more, need the content of research also more and more, the scientific research and design level that Geotechnical Engineering is built and the requirement of computational accuracy are more and more higher, and existing testing equipment aspect such as formed strain field scope and degree of uniformity in function load mode, model can not satisfy the needs of engineering practice well.
Summary of the invention
The utility model provides a kind of rock mass engineering project physical simulation experiment machine, to solve the problem that existing testing equipment aspect such as formed strain field scope and degree of uniformity in function load mode, model can not satisfy the engineering practice needs well.The technical scheme that the utility model is taked is: entablature, left side beam, right side beam, sill is respectively by the steel plate welding fabrication, and be connected with the gusset joint plate bolt respectively, the frame supported pin is fixedlyed connected with former and later two faces of gusset joint plate respectively, one end of lifting lifting jack one is fixedlyed connected with left side beam, the other end is fixedlyed connected with entablature, one end of lifting lifting jack two is fixedlyed connected with right side beam, the other end is fixedlyed connected with entablature, entablature, left side beam, right side beam and sill be inboard fixedlys connected 5 chargers respectively, test specimen case two ends respectively with left side beam, right side beam is fixedly connected, auxiliary big plate respectively with entablature, sill connects, at entablature and left side beam, entablature and right side beam, sill and left side beam, sill and right side beam junction be inboard fixedlys connected anti-interference 12 respectively; This charger adopts nine to load cylinder.
Advantage of the present utility model is novel structure, can carry out geomechanical model test to cavern, hole group's side slope and foundation ditch, adopted nine of servocontrol to load the synchronous loading structure of cylinder, solved the lifting jack of model test employing in the past preferably and loaded, pressure homogeneity deviation is bigger; Adopt flexible bags loading stroke less than normal, the technical barrier that intensity is on the low side; Solved effectively in the geomechanical model test, required the technical barrier that strain field is even, scope is big, degree of uniformity is high, preferably the simulate formation engineering be subjected to force environment, can satisfy the needs of national defence, civil air defense constructions and installations and large-scale civilian geotechnical study.
