Further, first end panel 131 is made with second end face plate of transparent material, so as to facilitate experimenter Observe the inner case of tunnel model experimental provision 100.
Damper assembly 150 includes two dampers.Two dampers are connected to each side on lateral plate component 110 with intersecting On the jointed shaft of plate.I.e.:One of damper one end is connected on the jointed shaft of the first side plate 111 and the second side plate 112, separately One end is connected on the jointed shaft of the 3rd side plate 113 and the 4th side plate 114;Another damper one end is connected to the first side plate 111 and the 3rd side plate 113 jointed shaft on, the other end is connected on the jointed shaft between the 3rd side plate 113 and the second side plate 112.
Further, damper two ends are hook formation, the jointed shaft of hook formation and each side sheet room on lateral plate component 110 Coordinate, that is, realize the connection of damper.
Specifically, damper is elastic component.
It should be noted that:In other embodiments of the present invention, the side plate number on lateral plate component 110 is not limited to Four, the side plate number of all detrusion that can realize tunnel model experimental provision 100 should be included in the protection model of the present invention In enclosing;
In the other embodiment of the present invention, the blade number on first end panel 131 is not limited to three, but can be with For any positive integer;
In embodiments of the present invention, it is that tunnel model experimental provision 100 provides resistance that the purpose for setting damper assembly 150, which is, Buddhist nun, can damp the damping group of form from elastic damping, viscous damping, plasticity damping, bullet-glutinous-plasticity associativity damping etc. Part 150, can also be set to rigid rope by damper assembly 150, when damper assembly 150 is set to rigid rope, and tunnel model is real Experiment device 100 is rigid box;
The purpose that first end panel 131 and second end face plate are set to transparent material is to be easy to experimenter to tunnel mould The inner case of type experimental provision 100 is observed, certainly, in other embodiments of the present invention, the He of first end panel 131 Second end face plate may be arranged as opaque material.
The pseudo-dynamic equation method of this use tunnel model experimental provision 100 comprises the following steps:
A. the first side plate 111 is opened, stratum simulation material is inserted in the cavities;
B. underground structure model is inserted in the cavities;
C. stratum simulation material is inserted in the cavities, stratum simulation material is covered the underground structure model;
D. tunnel model experimental provision 100 is fixed on ground, makes the first side plate 111 of tunnel model experimental provision 100 Upward;
E. in one end input displacement load where the first side plate 111.
After simulated formation material and underground structure model are filled, in one end input displacement load of the first side plate 111, this When tunnel model experimental provision 100 section produce deformation so that area diminishes, simulated formation material and underground knot in cavity Structure model will be all under pressure due to the deformation of tunnel model experimental provision 100.Force analysis is carried out to underground structural model, Can in sunykatuib analysis earthquake a certain instantaneous underground structure stressing conditions.
The essence of this analysis method is to carry out state mould in a flash to 100 certain in vibration of tunnel model experimental provision Static analysis is fitted, is the means analysis dynamic process by static analysis, therefore referred to as pseudo-dynamic equation.
Pseudo-dynamic equation of the prior art can only be carried out by online mode, the tunnel model experiment that the present invention is provided Device 100 and pseudo-dynamic equation method cause the real experiment for intending power to become in order to may, it is to avoid a variety of disadvantages of online experiment End.In addition, pseudo-dynamic equation method can carry out kinematic analysis by static(al) method, without opening shake table, so as to drop The low equipment requirement to laboratory, and greatly save experimental cost.
Connected mode due to each side sheet room on tunnel model experimental provision 100 is is hinged, therefore, in experimentation In, tunnel model experimental provision 100 allows stratum simulation material to become as shearing occurs for the vibration of tunnel model experimental provision 100 Shape, and this deformation process is closer to real processes, is not in the distortion phenomenon of " drawer type " slidably;In addition, , will not be because the rigidity of side plate and end plates is not enough and causes in experimentation because each side plate and end plates are rigid plate Enough restraining forces can not be provided for stratum simulation material, can also avoid producing " arching " due to the deformation of plate causes mistake Very, so that side plate applies pressure with the deformation of tunnel model experimental provision 100 to simulated formation material becomes in order to can Energy.
Further, in order to simulate the stressing conditions in buried or larger confined pressure tunnel, while step e is carried out, also It can follow the steps below:
F. pressure is applied to stratum simulation material.
Step f can be specifically achieved in that:
Inflating bag is put into the cavity that lateral plate component 110 and end face board component 130 are surrounded, stratum simulation material and mould is treated After plan underground structure is placed, inflation or topping up into inflating bag.Because each side plate and end plates are rigid plate, inflating bag Interior pressure will act on stratum simulation material completely, so that stratum simulation material is by static pressure, simulates buried or encloses The force environment in the larger tunnel of pressure.
Specifically, inflating bag can be air bag or water pocket.
It should be noted that in pseudo-dynamic equation method, step a, step b, step c, step d order can have respectively Plant and change, in the range of the thought of the present invention, the numbering of each step is not comprising the restriction to implementation order, this area to more than Technical staff can adjust to the implementation of above step order according to actual needs, these adjustment all should the present invention guarantor Within the scope of shield.
The preferred embodiment of the present invention is the foregoing is only, is not intended to limit the invention, for this area For technical staff, the present invention can have various modifications and variations.Within the spirit and principles of the invention, that is made is any Modification, equivalent, improvement etc., should be included within the scope of the present invention.
