Description
Technical field
The present invention relates to floatation type offshore wind turbine anchorage technology field, and in particular to a kind of suction caisson with four-bladed vane
Basis.
Background technology
Floatation type basis applies in general to off-lying sea marine site, or the sea water advanced marine site more than more than 50m, and this is accomplished by one kind
Reliable base form provides anchoring for floatation type blower fan.
The anchoring piece of floatation type offshore wind turbine is most of in global range adopts gravity type foundation and pile foundation, due to gravity
The delivery of formula basis is difficult, and cost is higher；Pile foundation construction needs Large Construction ship to be driven piles, in the face of severe sea situation bar
It is deeper that part, the long high cost of piling work construction period, and pile foundation enter mud so that pile foundation cost is very expensive.How effectively to reduce
Floatation type offshore wind turbine anchor system cost is into important research topic.
Suction caisson foundation size range is wide, bearing capacity is big, the limit depth of water is big, it is little sea bed to be affected in installation process,
Can apply in the case of various soil properties and repeatable utilization, these are all that traditional pile foundation and gravity type foundation do not have
Advantage.Additionally, suction caisson foundation low cost, installation equipment is relatively easy, and installation period is short.Under deep water conditions, anchor
Pool system is more economical, and it is convenient that installation is also relatively driven piles, and suction caisson foundation is widely used anchor in deep-sea oil gas exploitation
Pool basis.
The vertical anti-pulling capacity of suction caisson foundation, mainly there is side friction, cohesive force and negative pore water pressure group
Into, the vertical failure mode of general suction caisson foundation has three kinds of forms, when suction caisson foundation rate of loading it is slow, cylinder
Interior negative pressure and soil body pore water pressure fully dissipate, and at this moment basis occurs local shear failure, and its anti-pulling capacity is often relatively low,
Main reassembling into certainly by the frictional force between cylinder inside and outside wall and the soil body and anchor.When the rate of loading of suction caisson foundation increases,
Negative pressure part dissipates but the soil body in cylinder is moved together with cylinder enough in cylinder, and at this moment basis occurs bottom tensile failure, and it resists
Bearing capacity is pulled out by bottom stretching resistance, the frictional force composition between the deadweight of cylinder and soil plug and basic outer wall and soil.When suction anchor quilt
When quickly extracting, negative pressure and soil body pore water pressure have little time to dissipate in cylinder, and at this moment basis occurs overall destruction, its bearing capacity
It is often maximum, by the deadweight of soil plug in cylinder and cylinder, the part of backward bearer power three composition of frictional force and soil between drum outer wall and soil.
But under long-term vertical uniform load q, the negative pressure in bucket gradually dissipates, cylinder vertical bearing capacity only by wall friction power with
Cylinder is from reassembling into, and bearing capacity is relatively low, and steel waste serious.
