Design of Vibroflotation
Vibro compaction
The design of vibro compaction method is mainly based on experiment and engineering practice.
Compaction depth:
The stress distribution and foundation soil strength can be determined according to the load of upper building.The formula of calculation is accorded to the standard of building foundation.
Compaction scope:
1) the strip foundation or independent foundation can only be used in the base range.
2) raft base and box base are usually piled on the whole foundation, and 1-3 rows of bollards can be arranged according to the need.
Space of piles and piling method:
A normal triangular or square style layout is generally adopted.There are several methods for pile spacing design:
1) field test method.
2) estimation of filling volume.
3) empirical formula method.
