Description
Technical field
The utility model belongs to technical field of civil engineering, and in particular to a kind of bridge pier for resisting mud-rock-flow-impact.
Background technique
Mud-rock flow is that one of highest natural calamity is endangered in mountain area.Due to natural calamities such as earthquake, volcano eruption, floods or
The irregular engineering activity of the person mankind causes, the special mighty torrent of typical case being made of the water of high concentration, mud, sand, gravel impurity etc., past
Toward having the characteristics that sudden and randomness, the process of formation is also sufficiently complex, general speed is fast, destructive power is strong and flow compared with
Greatly, huge energy and destructive power are produced in the process of flowing.The geological conditions in mountain area is again increasingly complex more compared with plains region
Become, plate motion, seismic activity, in addition mankind's long term activity of earthquake, soil is barren, vegetation coverage reduces, and significantly increases mud
The probability of happening of rock glacier.2/3rds or more of China's national territorial area are mountain areas, and mudstone flow phenomenon is wider in the world
One of general country, mud-rock flow are mainly distributed on the mountain area area in China western part and North China.
Important tie of the bridge as road intercommunication, is destroyed by rush of water, and in successive years by mud-rock flow often, has and increase year by year
The trend added.The impact energy that mud-rock flow not only relies on its powerful can directly destroy by rush of water bridge culvert architecture, cut pier, push over beam
Body can also become silted up and bury bridges and culverts, reduction under-clearance, batture, and the substances such as stone mud being mingled in mud-rock flow can also block bridge
Hole reduces the discharge capacity and service life of bridges and culverts；And no matter pacify from traffic and transport economy or human life's property
Entirely, it is huge for losing caused by all.
It in the design phase is under normal circumstances to require to pass round as far as possible for the bridge in mud-rock flow area, when mud-rock flow must be passed through
Qu Shi while should reinforcing monitoring and forecasting, is based oneself upon locally, based on arranging, the principle that guide shield combines.
At present bridge pier prevent mud-rock-flow-impact destroy there are several types of technical measures:
One, the region influenced by mud-rock flow is passed round as far as possible in bridge route selection, make bridge route far from debris flow gully region.
The technical measures are possible to the exacerbated entire line condition of meeting, certainly will increase line length and construction investment, there is also and apply
The very big situation of work difficulty.
Two, bridge pier is not arranged across debris flow gully is crossed in debris flow gully using Longspan Bridge one.The technical measures are not
It is only influenced by technical solution, can also be influenced by geological conditions such as mud-rock flow area landform, gully width, absolute altitude, rock soil properties,
It eventually leads to difficulty of construction greatly or construction investment increases severely, cause this scheme invalid.
Three, the prevention and treatments for taking engineering measure to carry out mud-rock flow at present more, common are block, arrange lead, protect, biological structure
Deng.Due to the complexity of mud-rock flow, the feature of different zones mud-rock flow is often far from each other, therefore, although being directed to different mud
Rock glacier basin devises corresponding engineering structure, but when mud-rock flow occurs, it is also possible to cross engineering measure layer by layer, directly
It impacts on bridge pier, the safety of bridge cannot still ensure；Simultaneously as prevention and cure project is generally along debris flow gully scattering device, dimension
Protecting difficulty may be larger.
Current existing measure can play reduction really, weaken mud-rock flow generation and ability and other effects of causing disaster, but due to
Suddenly rain cats and dogs, the natural causes such as earthquake influence, still can happen suddenly mud-rock flow, and uncertain big, scale is constantly aggravated, and may be used also
It can cross and protect layer by layer, directly impact bridge pier, simple puts up a resistance by bridge pier, can not solve mud-rock flow pair from the root
In the shock problem of bridge pier.
