Description
Technical field
The present invention relates to traffic base construction fields, flexible in particular to a kind of meizoseismal area Cross-fault leveling tunnel-liner
Expansion joint device and tunnel lining structure.
Background technique
Tunnel Engineering is typically considered the superior engineering construction of anti-seismic performance, but under the conditions of macroseism, tunnel earthquake tune
Bright Cross-fault leveling section tunnel structure earthquake of tabling look-up is obvious.When tunnel and underground structure pass through fault belt location, by tomography
It influences that the lineament in tunnel is made to occur shear-deformable and destroy.When earthquake occurs, position of the tomography in tunnel structure position
Mistake amount generally differed by several centimetres to tens meters, pass through the underground structure body of fault belt during fault movement, by because
It directly bears powerful extruding when country rock ruptures or pulls, and generate unavoidable destruction.
Infrastructure climax is in the ascendant, and passing through active fault region structure design of tunnel method is high intensity Zone tunnel
The major issue that one of road engineering construction is hard to avoid both at home and abroad.For example, and being in the Sichuan-Tibet iron in survey and design stage
1629 kilometers of Lu overall length, bridge tunnel is also up to 42.5%.Only Sichuan-Tibet railway just will be travelling through including that fresh root yield, Ganzi-cajaput are disconnected
It splits, Litang fracture, Batang fracture, Yulong wish that fracture, Baxiu County's fracture, Jiali fault, Milin-Lu Lang fracture etc. are a plurality of movable to break
It splits or fracture belt.Middle diplomatic relations build in the Kenya undertaken the construction of malleable iron road across famous East African Rift Valley east branch, the East African Rift Valley
Maximum fracture belt on world land.A large amount of normal fault is developed along rift valley trend, mature fault is long, and width is big, and spacing is close,
More active, a plurality of tunnel spanning active fault dislocation amount of design reaches 0.9m or more.
In the existing construction for passing through active fault Tunnel Engineering, in order to reduce faulting to the shadow of tunnel structure
It rings, mainly uses cross section to dig and the engineering measures such as varistructure design in active fault region.Wherein, cross section digs master
Will be tomography changing of the relative positions reserved space, with guarantee tunnel cross-section headroom and boundary requirement, belong to passive design, dig range and
Area is related with cross dimension and fault predicting changing of the relative positions amount；And the design of the special constructions such as varistructure then belongs to a kind of active and arranges
It applies.
Turkey wins Lu's vcehicular tunnel within 2002Nearby it is divided into using lining cutting with Bakacak active fault
Multiple segments simultaneously resist disconnected protection design with the relatively small flexible connection of rigidity.Iran's Koohrang-III water delivery tunnel in 2005
Road also uses the design of flexible joint when passing through active fault crushed zone.The method that flexible joint is arranged is to try to reduce tunnel
Road segmental length makes a certain range of segment of fault belt and its two sides keep relatively independent.In fault movement, destroy
The part for concentrating on connecting portion or tunnel structure is destroyed without will lead to globality.Tunnel structure can on the one hand adapted to disconnected
The seismic deformation that layer generates；On the other hand eaerthquake damage can be made to localize.
The Tunnel Engineering that bad geological section is more passed through in domestic and international meizoseismal area is made a general survey of, the design experiences of shock resisting can be summarized as cross
To " digging " and longitudinal " hinged " two major classes.When the tomography of the larger changing of the relative positions amount of Tunnel Passing, individually digged using cross section
Mode will cause tunnel excavation face is excessive, increase planform mutation be unfavorable for liner structure safety.Varistructure is
One kind can all kinds of active faults of flexible adaptation, and be capable of the engineering measure of effectively item controlled cost, but existing design stops
It stays in the theory of " hinged " design, it is thus necessary to determine that hinged pattern simultaneously guarantees comparable static(al) bearing capacity；The set of certain applications
Cylinder design is again departing from the thinking of " flexibility " design.Therefore, change the design form of conventional tunnel structure, enhancing structure integrally resists
Shock stability innovation flexible joint structure type is the key that pass through active fault tunnel to carry out shock resisting.
It is existing to be on " soft " across active fault tunnel flexible joint design key, it is substantially takes ratio at this stage
The small structure design of liner structure rigidity, there are no practical application and reliable related ends for articulated joint (sleeve) design.But
The essence of " soft " property design is not that rigidity reduces " rigidity flexible design " instead of, is " displacement flexible design ", namely:
Connector in fault movement, the motion displacement for following country rock can be generated when strong earthquake motion, that is to say, that flexible joint tomography mistake
Certain displacement can be actively generated under dynamic to offset structure caused by fault movement and influence；Become in strong earthquake motion effect lower contact
Shape can effectively cut down the influence of tunnel structure tension and compression, shearing, bending and torsion.Engineering practice and theory analysis all surfaces are only reduced
The flexible design of joint stiffness can not bring preferable shock resisting effect, or even since rigidity reduction causes connector and linkage section
The insecurity of bigger earthquake and static load.It is proposed that flexible joint of the invention is set based on new " displacement flexible design " theory
Meter.
