pability and further solve the shortage of urban land.In high-rise buildings,special soil can be
used to ensure the stability of the building structure and increase the ultimate bearing capacity of
the foundation.The ultimate bearing capacity of the supporting structure for the silty clay foun-
dation was tested to improve its analysis accuracy.Firstly,the silty clay sample was prepared,
loading devices were selected,and the on-site loading data collection and related calculation meth-
ods were proposed.Finally,the test results were obtained to complete the ultimate bearing ca-
pacity analysis.The results show that the ultimate bearing capacity of single pile is 200 MPa,and
the characteristic value of the bearing capacity of single-pile composite foundation ranges from
225 MPa to 250 MPa.In addition,the relationship between foundation load,settlement,and stress
ratio was also obtained,which could provide useful reference for the design and construction.
Key words:silty clay;foundation;supporting structure;load;ultimate bearing capacity
