Study on load bearing characteristic of cast in situ DX group pile with numerical analysis

Zhang Qinglin,Chen Lihong

Strategic Study of CAE 2012, Volume 14, Issue 1,   Pages 51-59

Abstract:

This paper analyzes 4 types of group-pile which contains 4 piles withThe main conclusions are: group pile effect of DX pile increases sharply when pile spacing decreases；the bearing capacity of 3D spacing group-pile is 1.32 times larger than that of 1.5D spacing group-pile；effect coefficient of group-pile increases from 0.59 to 0.78 when spacing increases from 1.5D to 3D；the maximum value of settlement of soil among group-pile occurs between two bearing plates, and it decreases

Influence of axial load on the lateral pile groups response in cohesionless and cohesive soil

Jasim M. ABBASA,Zamri CHIK,Mohd Raihan TAHA

Frontiers of Structural and Civil Engineering 2015, Volume 9, Issue 2,   Pages 176-193 doi: 10.1007/s11709-015-0289-7

Abstract: The improved plots can be used for lateral loaded pile design and to produce the group action designThe effect of load combination on the lateral pile group response was performed on three pile group configurationsgroup behavior using improved p-multiplier.It was found that the group interaction effect led to reduced lateral resistance for the pile in thegroup relative to that for the single pile in case of pure lateral load.
