Description

The bionical reinforcing bridge in a kind of tunnel
Technical field
The present invention relates to a kind of structural member of construction of tunnel, particularly relate to a kind of girth member structure that shield tunnel is vertically increased rigidity.
Background technology
At present, to run for a long time and produce the excessive deformation problem be a world-class difficult problem to the control soft soil tunnel.For preventing that serious deformation from reaching the threat of subsidiary secondary disaster with the operation that ensures safety, each state has all taked active measures, what Japan taked is the double-deck lining cutting ring of cast-in-site steel concrete, what Holland adopted is stub basis single shell lining ring, Germany has then adopted shield method and individual layer pin-connected panel, and what adopted as domestic first hand weak soil constructing metro tunnel unit in Shanghai is German pattern and straight joint splicing.With the tunnel, Shanghai is example, estimate before the commencement of works that the most good sunken amount is less than 5mm, actual operation after 5 years the largest cumulative settling amount surpass 200mm already, remove about the ground settlement amount 100mm same period actual shaking and fall into also tens times of the amounts of exceeding the estimates, annual maximum difference settling amount can reach 30mm.More dangerous is that this vertical differential settlement does not still have smooth trend so far, and the ring plate that causes thus cracking and seam seepage flow have aggravated sedimentation once again.Situation is very severe, and maintenance and reinforcing task are urgent.There is academician's chapter of sending the documents to appeal that each the row expert and the whole society pay close attention to this problem at the design in the reinforcing of operation tunnel and new tunnel.
Studies show that longitudinal rigidity resistance to deformation and the sedimentation effectively that improves Shield Tunnel in Soft Soil, this is present numerous scholars' a common recognition.Control soft soil tunnel large deformation problem derived the tunnel vertically theory and the method for design have much rich grade of intelligence in the representational village that Japan arranged and propose, and the beam-spring model of series connection applies to the vertical structure design in tunnel; Also strong-willed ripple is by equivalent axial rigidity model on the elastic foundation of propositions such as a discipline husband and island, river one man of virtue and ability.It is the theoretical foundation of present domestic and international application research that these two kinds of linear elasticities vertically design a model.
How to improve the longitudinal rigidity in weak soil individual layer the old and new tunnel, domestic scholar advocates high performance material, the peripheral reinforcing in tunnel and adopts staggered joint erection etc., Guangzhou that had just put into effect in recent years and Line of Nanjing Subway just are modified into fissure of displacement splicing than Shanghai Underground, and this fissure of displacement is more favourable to the increase of tunnel lateral direction rigidity.According to supervising first-line abundant experience at subway for a long time, there is document to point out that the curve of tunnel differential settlement is not that the displacement of every joint ring plate generation relative rotation constitutes fan-shaped flexural deformation, be that faulting of slab ends forms between ring plate, that is the flexural deformation that relative translation constitutes has taken place between ring plate.And advocate the ring plate connection that design has the convex-concave edge of table, can be controlled at the faulting of slab ends amount of every ring in the safety value 4-8mm scope.But the catastrophe of reduction suddenly will take place in the longitudinal rigidity in tunnel when every ring faulting of slab ends amount surpasses 8mm.It is domestic up-to-date argument that this utilization " convex-concave edge of table " increases longitudinal rigidity, and the ACTIVE CONTROL scheme is attemptable for new Tunnel Design, is infeasible for a large amount of operation tunnel in Shanghai.
The shield tunnel of prior art is to be formed by connecting by reinforced concrete prefabricated a large amount of pipe sheet assemblings, each ring tunnel is generally formed by six pipe sheet assemblings, it is respectively the jacking block in top, about two adjacent block, be two calibrated bolcks and an arch bottom more successively, to upper and lower 16 degree and 84 degree of being respectively of the central angle of shape, four of both sides each 65 degree.The thickness of section of jurisdiction is 350mm, and the branch of the straight joint and the fissure of displacement is arranged in shield structure assembly unit process, and latter's mutual dislocation has improved some intensity and rigidity.
The vertical differential settlement in Shanghai soft soil tunnel does not have the stable tendency problem; not only strengthened the maintenance cost of operation tunnel; it also is the major hidden danger of tunnel safety operation always; constantly perplexing the each side scholar, comprising that authoritative sources such as famous academician appeals " actively developing and the relevant scientific research of subway protection " in article.Open settling amount problem go fromes bad to worse if things go on like this in case that the disaster consequence takes place is hardly imaginable, we are " the courageously disaster relief " always, should on preventing and reducing natural disasters, make an issue of more and do article, with the essence of the civilization that embodies Shanghai international metropolis and " allow life finer ".The same earthquake calamity had once attacked Haiti and New Zealand, caused different result, the experience of the zero death rate reference that is worthy of our study very much under the big shake of the latter.Funds that are used to prevent and reduce natural disasters and time are many more also well below the input of " the courageously disaster relief ", and the social effect of being received is incomparable especially.How further to improve the longitudinal rigidity in weak soil individual layer the old and new tunnel, the reinforcing technique that particularly can be applied in the old tunnel is the problem of pendulum sternness in face of those skilled in the art.
Summary of the invention
The objective of the invention is to propose a kind of subway tunnel that can be used for new building at vertical uneven subsidence of tunnel in the weak soil and pipeline, can transform, improve the tunnel reinforcement structure of a kind of bionics techniques of rigidity and intensity again to old tunnel, purpose of the present invention is realized by following technical scheme.
