Description
Technical field
The present invention relates to a kind of method preparing simulation roadway deformation empirical model, be particularly useful for the resemble simulation test of laboratory about roadway bolting support.
Background technology
For the rule of research roadway deformation, movement and destruction, especially to relating to elastoplasticity, fragmentation, the rock mass mechanics problem of the how middle physical mechanics process to have various forms cavity structure such as being caving, analog simulation is utilized to be a kind of effective research method.By contacting between rockbolt stress and superincumbent stratum activity can be sought to anchor pole and the interactional modeling effort of country rock, also seek to change the affecting laws to roadway deformation after a certain supporting parameter by the analogy test of several model.
In tradition similarity simulation experiment, applying the method for anchor pole has pre-buried and in the after-applied two kinds of methods of laneway molding.The method of tradition embedded anchor bar element accurately cannot be located anchor pole element, and in model process of deployment, anchor pole element often can produce and move and the position of off-design, and anchor pole element cannot be made to expose certain length.If at the after-applied anchor pole element of laneway molding, then must punch in tunnel, due to the restriction of moulded dimension, punch very inconvenient, considerably increase the workload that model is laid, and wall can be caused uneven, the stress easily forming local in the process of pressurization is concentrated.

A. when the filling simulation material in model casing is fills up to desired location, in the position in setting simulation tunnel, the middle part of model casing, place the simulation tunnel element of setting size, the section of simulation tunnel element is rectangular drum like body, is provided with the plank of multiple anchor pole component hole in the arranged on left and right sides and tip position of simulating tunnel element respectively;
B. from arranged on left and right sides with multiple anchor pole component hole plank bottom plug-in mounting head with the anchor pole element of hook, until top plank with holes, in model casing, fill simulation material simultaneously, limit plug-in mounting anchor pole element, simulation material is filled on limit, until fill simulation material to be full of model casing, and compacting;
C. simulation material to be filled shaping after, extract simulation tunnel element out, and take off plank, complete the model preparation in simulation tunnel.
The described plank with multiple anchor pole component hole is multi-layer solid wood composite board, and plank thickness is equal with the revealed section length that test sets anchor pole element, and plank length is equal with the length in simulation tunnel.
Described anchor pole element adopts fuse, iron wire or steel wire to make.
Beneficial effect: owing to have employed technique scheme, the present invention compared with prior art has the following advantages:
(1) position by plank is holed controls the position of anchor pole element in tunnel, and it is fast that speed laid by the accurate positioning of anchor pole element and model, and tunnel surface smoothing is neat, and model is more attractive in appearance;
(2) in the process that model is laid, can the accurate position of positioning anchor rod element in tunnel;
(3) thickness by adjusting plank controls the protruded length of anchor pole element, is convenient to the original paper such as tray and nut.
