Application of Rigid Inclusion Composite Foundation of High-Raised Buildings in Soft Soils
The rigid pile composite foundation is widely used in soft soils as the foundation of various buildings and highways.But in high-rise buildings,the load acting on the foundation is large,and when the local stratum is too weak,considering the complexity of the composite foundation interaction,the bearing capacity of composite foundation is usually having problems.This paper presents a case history of the application of rigid inclusion composite soil as the foundation for a high-raised building by using the relevant tests and the numerical analysis methods.The bearing capacity of the composite foundation under differ-ent soil layers and the soil load acting on the single pile and among piles are obtained.At the same time,considering that the construction of rigid inclusion in soft soil layer is usually have different quality problems,which requires a high level of experi-ence of construction personnel and is difficult to deal with quality defects.It is not recommended to use rigid inclusion compos-ite foundation as the foundation for the high-raised buildings in the too weak soil strata.
