Background technique
The deeper super-giant foundation pit of area super large, depth, such as the board-like supporting+inner support used according to conventional foundation pit
Retaining design will occur the problem that
The large-scale excavation inner support system interim armored concrete or bracing members that need the big scale of construction first, this will raise whole
The cost of a engineering；Secondly bearing length is too long, and slenderness ratio is excessive to cause rigidity to weaken seriously, can not provide for enclosure wall enough
Counter-force；Bearing length is too long again, and under responsive to axial force, the compressive deformation of itself reaches several centimetres even tens centimetres,
Excessive so as to cause braced wall deformation, supporting construction failure risk greatly increases.
The existing center island method of engineering circles can solve that super large area deep foundation pit support system cost is excessively high and safety compared with
Low problem.This method makes central island regions be excavated to hole bottom absolute altitude in the reserved soil in foundation pit border skirt, and using multi level slope, so
Construction central island underground structure afterwards, after central island structure construction to basement roof, then excavates the border soil body and the area that constructs
Domain underground structure beam slab.Method is estimated to reserve the earthwork by border to go along with sb. to guard him the deformation for providing and being reduced foundation pit by counter-force of breaking ground.But
There are rheological behaviors for the soil body in soft clay area itself, are saturated soft clay itself and are persistently deformed with the growth of time,
And overlarge area foundation pit construction period itself is longer, this will lead to the reserved slight slope in foundation pit border and persistently generates displacement, cause to go along with sb. to guard him
For structure long lasting for deformation, it is unfavorable to protect to surrounding enviroment.Simultaneously in order to ensure slight slope self stability is reserved in foundation pit border,
A large amount of slopes reinforcement measure is needed, is not economically quite reasonable.
