Description
Technical field
This application involves tunnel structural model technical fields, and in particular to a kind of shield tunnel vertical structure character model examination
Experiment device and its application method.
Background technique
Stratum locating for shield tunnel is in certain natural strain condition, before tunnel does not tunnel, primary stress field and ground
It is lauched seepage field and is in opposing stationary dynamic balance state.Shield tunnel construction destroys dynamic equilibrium between the two, into
And it generates and inducts stress field to maintain the mechanical balance on stratum.It is put down to restore the dynamic of this effect system of seepage field Yu stress field
It weighs, must be just able to achieve by certain coupling between double fields.The coupled problem of country rock and underground water can make point of load
Boot levies the variation that changes a lot.
In structure design of tunnel, often according to plane strain it is assumed that taking a few ring tunnels is research object, by research object
Force analysis result as design considerations, and the less longitudinal stress and deformational behavior for considering tunnel.In fact, being embedded in soil
Shield tunnel in layer is a slim-lined construction along longitudinal direction, flexible larger, is affected by the ambient and is more easily deformed,
And it then will lead to structural damage when the deformation increases to a certain extent.Compared with the circumferential deformation characteristic of section of jurisdiction, shield tunnel
Vertical characteristics it is more fragile and its consequence is often unfavorable to tunnel structure.The shield tunnel largely runed is excessive because generating
Sedimentation or inhomogeneous deformation, to induce, infiltration leakage mud, structure partial fall off destruction or internal structure occurs buckling and becomes
Shape all has a certain impact to the structure safety, the operation security of train and comfort level in tunnel.Excessive segment deformation, then easily
Cause long rails height difference excessive, also make the flatness of track exceeded, aggravates the abrasion of wheel.Construction disturbance, stratum unevenness and water
Position variation is the principal element for causing tunnel linear deformation excessive.
The research of duct pieces of shield tunnel structural test is mainly based on prototype test and layer during similar model test.Prototype test is most
Directly, most effective research technique, it being capable of actual response section of jurisdiction stress deformation situation；But since prototype test scale is big,
It is at high cost, and full-blown equipment is needed to load, so that the prototype test scope of application is restricted.Model test is with similar reason
Based on, various relative complex boundary conditions can be simulated, can relatively comprehensively and visually present engineering structure to it is related
Stress and deformation mechanism, failure mechanism under Rock And Soil collective effect etc..For a long time, model test method is always to study solution
The important means of certainly large complicated ground and Structural Engineering project.Shield tunnel testing program design theory basis selection,
The selection of Structural Test of Tunnel Segments, the preparation of model soil material, loading scheme and simulate operating condition determination and boundary condition letter
The problems such as change are a complicated system engineerings.

Influence of the soil medium to model tunnel；Moreover, failing the coupled problem of consideration soil layer and underground water.Secondly, most of shields
Structure tunnel model does not simulate the longitudinal joint that section of jurisdiction is formed in actual tunnel and circumferential weld and erection method, can not consider or be difficult standard
