Description

A kind of reservoir landslide intelligence dewatering well
Technical field
The utility model belongs to preventing land slide technical field, and in particular to the flowing pressure type influenced by water level fluctuation of reservoir The intelligent dewatering well on landslide.
Background technology
It is large-scale especially in the strategic decision implementation process of " development of the West Regions " with economic construction of China high speed development Hydraulic and hydroelectric engineering takes place frequently area's construction in complex geologic conditions, Landslide Hazards in succession, while bringing great economic benefit Also many reservoir landslides are induced in reservoir area.
Reservoir landslide is due to its special reservoir area hydrologic condition, the deformation of reservoir landslide different from general landslide, side slope Evolution can show periodic regularity with the fluctuation of reservoir level.Reservoir area of Three Gorges in China, (such as plain boiled water river is slided on a large amount of landslides Slope, loess slope landslide etc.) monitoring materials show, obviously aggravate in Drawdown of Reservoir Water Level phase Landslide Deformation, and the reservoir level rising stage Hardly increase with stage of stable development deformation, global displacement curve is in " phase step type " changing rule at any time.This is because under reservoir level When drop, the level of ground water in slip mass often lags behind the decline of reservoir level.Cause landslide middle part level of ground water and reservoir level it Between head difference increase, to generate be directed toward slope outside osmotic pressure, increase the sliding force on landslide.So it is past to come down in reservoir area It is towed more than top that lower deformation is also shown as toward forms of motion.
Common landslide control measures have the measures such as antiskid control structure, surface drainage ditch, leading edge bank protection in engineering at present, Antiskid structure measure is mainly based on friction pile.The operation principle of friction pile be for stake after gliding mass enough skid resistances are provided, Stability from the angle of stress field control landslide, this measure is for thrust load caused landslide effect of the Thrust of Landslide from middle and back Obviously.But the flowing pressure type to play a leading role for seepage field comes down, and since its forms of motion is generally towed, is being implanted into After friction pile, gliding mass still can constantly deform under the influence of library water acts on before stake.The deformation of gliding mass can cause friction pile before stake The missing of resistant force in front of anti-sliding pile makes the long-time stability of landslide-friction pile system be difficult to be protected.
Inventor has found, in reservoir geological calamity harnessing project, comes down for flowing pressure type or using tradition The measures such as friction pile administered.Although can empirically properly increase safety stock when designing friction pile, increase friction pile Skid resistance, but this way is palliative, does not only have preventive and therapeutic effect to gliding mass before stake, but also can cause economy Waste.Further, since the Dominated Factors on flowing pressure type landslide are underground water, acted in long-term periodical water level fluctuation of reservoir Under, periodically variable dynamic osmotic pressure forms a kind of CYCLIC LOADING for landslide and friction pile, and in cyclic load Under the long-term safety of landslide-friction pile system be difficult to be protected.It is traditional but due to reservoir level cyclically-varying Subdrainage method is difficult to apply to reservoir landslide harnessing project.
