Influence of Pile Spacing and Pile Cap Width on Bending Moment of Pile for Pile-net Composite Foundation

Taking the treatment engineering by pile-net composite foundation against the deep soft soil in extra-large area at the railway station in a coastal city in Guangdong as the example,the influence of the pile spacing and the pile cap width on bending moment of the pile body is studied with FLAC3D numerical analysis software.The study findings include that the increment of pile spacing will give rise to the increment of bending moment,while the increment of pile cap width will reduce the moment;however the change of pile spacing affects the moment more significantly.
