Application Study Of Soil Pressure In Consideration Of Spatial Effect In Double-row Piles Support

It is increasing number of high-rise building, super high-rise building, underground build, large type dock and so on along with economy development of our county. So, the increasingly dug project of large type foundation. It is nicer effect that double-row piles supporting structure in application of digging foundation, but at present, it is lack systematic study about stress mechanics, reciprocity of piles and soil, calculation method of double-row piles supporting structure.Starting with soil pressure theory, it is calculation in double-row piles supporting structure by using soil pressure of spatial effect, and it study distortion and endogenetic force of double-row piles supporting structure by calculation result compare of spatial effect soil pressure theory and classical soil pressure theory. It obtains some availability conclusion by discussing infection of pile rigidity, ring beam rigidity, soil body reinforcement and so on of double-row piles supporting structure.By project example, first, it validates rationality of double-row piles supporting structure calculation with spatial effect soil pressure;second, it puts forward some availability advice of design and construction.
