Description
Technical field
The invention belongs to Railway Tunnel field of engineering technology, and in particular to a kind of high speed for passing through large-scale activity tomography
Track deformation control structure in railway tunnel.
Background technique
With the Large scale construction of the continuous development of railway construction in China, especially high-speed railway, so that railway tunnel
Number of applications is more and more.In the construction of Tunnel Engineering, meizoseismal area or fault belt are inevitably passed through
Situation, since underground structure is extremely difficult by the reparation after eaerthquake damage, rehabilitation cost is higher, to underground structure
Earthquake research, the tunnel earthquake research of especially high intensity Zone is very necessary.
When Tunnel Passing active fault, especially weak broken region, due to the geological conditions difference of country rock, occur
When geological process, the seismic response of tunnel structure is very big, especially passes through the section of soil, (the soft, hard) boundary of rock, is engineering structure
The dangerous position of antidetonation, these structure sections are often possible to that very big deformation and internal force can be generated.Therefore, it is broken how to reduce tomography
Influence of the broken band to tunnel structure stability and safety is the difficult point of structure design of tunnel and construction, especially to passing through tomography
The tunnel structure of crushed zone, which carries out seismic response analysis and the shock resisting measure of the section, seems particularly significant.
To prevent tunnel structure from destroying, when mountain tunnel passes through active fault or fractured weak zone at present, spy is generally required
The structure in different design tunnel or track, or the supplementary structure that setting is additional.Currently, common processing method has following three kinds:
1, flexible joint structure, such as large deformation ring, the lining cutting which allows its both ends to connect are set at soil, rock boundary position
Occur to stretch in a certain range, be displaced caused by compression and shear action, the ground of remaining section structure of tunnel is reduced with this
It rings and answers, this method is suitable for soft, the lesser situation of hard boundary position span, otherwise due to Shape-changeable ring limited length, antidetonation
Effect substantially reduces；2, it carries out section to dig, be digged by carrying out section in fractured weak zone or soft, hard mutation section, directly
Increase the reserved space for digging section liner structure Yu other section structures, this method allows to dig section liner structure in geological process
When be sufficiently displaced, dig the seismic response of section liner structure to greatly reduce, but this method be only applicable to shear-zone span compared with
Small situation, if passing through large-scale activity fracture belt, huge excavated volume will be generated by digging tunnel cross-section, and engineering is caused to make
Valence dramatically increases, and when geological process is larger, and since tunnel structure rigidity differs larger with country rock, tunnel structure more holds
Easy recurring structure destroys；3, tunnel structure buffer layer is set.The modulus of shearing of usual buffer layer is lower, when geological process, country rock
The changing of the relative positions occurs, is reduced by the sliding deformation that buffer layer buffering passes to tunnel structure, thus achieve the purpose that damping, but by
Increase construction investment cost in being laid with damping layer material, apply in general to the lesser region of active breaking belt span, if activity is disconnected
It is larger to split band span, construction cost certainly will be will increase dramatically.
In addition, although the setting of flexible joint structure can solve to pass through the tunnel knot of large-scale activity tomography to a certain extent
Structure stability problem, still, since the track in tunnel is often connected with tunnel by track plates and concreting, one
When denier earthquake occurs, related track the changing of the relative positions can occur together for tunnel structure when being subjected to displacement, and cause track that serious torsion occurs
It is bent；Along with the rate of traffic flow of high-speed railway is big (unidirectional 5 minutes one time general), running speed is high, and braking distance is long, if ground
Train is just by the location when shake occurs, even if train takes emergency braking measure in advance, train also can very likely be sent out
Raw derailment accident results even in train overturning and hits tunnel wall, tunnel structure is caused to destroy, and then causes more tight when serious
The secondary disaster of weight.Therefore, existing be set to passes through the tunnel structure of large-scale activity tomography and is unable to fully meet the section tunnel
Safety and stability in use process, has some limitations.
