Description
Technical field
The utility model belongs to the geomechanical model test device.
Background technology
Geomechanical model testing technology is the important means of the large-scale geotechnical engineering problems of research, at home and abroad be used widely, and in engineering scientific research and design and demonstration, brought into play vital role, domestic, external many units have all successively carried out the experimental study work of geomechanics model, and have developed the supporting model test equipment that scale does not wait.The kind and the pattern of geomechanical model test equipment are many both at home and abroad in general, see from the model modes of emplacement to be divided into: horizontal, vertical two classes; From the model load mode: mainly adopt lifting jack to load, minority loads with the hydraulic pressure capsule; From the counter-force mode is provided: metal frame posture and foundation ditch formula are arranged, and from the stressed dimension of model: major part all is two-dimentional, and from the plane strain condition of controlling models: it is few that strictness reaches, and adopts the directrix plane strained condition mostly; Strain field degree of uniformity and the homogeneity range of producing in the model: generally all smaller, yet 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, 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, therefore presses for the Geotechnical Engineering testing equipment of a kind of function admirable advanced technology of development.
Summary of the invention
The utility model provides a kind of rock mass plane layer during similar model test device, to solve the problem that present 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: side loads cylinder and is connected with frame fixation respectively, the lateral shift measurement mechanism loads cylinder with side and fixedlys connected, the side load plate is fixedlyed connected with side loading cylinder and is slidingly connected with framework, transverse baffle is connected with frame fixation, last loading cylinder is connected with frame fixation respectively, apparatus for measuring vertical displacement is fixedlyed connected with last loading cylinder, last load plate is fixedlyed connected with last loading cylinder and is slidingly connected with framework, and perpendicular baffle plate is positioned at the transverse baffle outside and is connected with frame fixation.During use, tested ground sample is placed in the device, on load the cylinder string on an oil circuit, side loads the cylinder string on another oil circuit, supplies with oil pressure, tests.
The utility model has the advantages that novel structure, this device can carry out geomechanical model test to cavern, hole group's side slope and foundation ditch, can carry out shearing resistance, anti-reflecting bending strength test to anchoring body imitation specimen and reinforced concrete member etc. after the function expansion; This device has adopted synchronous loading structure, has solved the lifting jack of model test employing in the past preferably and has loaded, and 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.
