A platform for research: civil engineering, architecture and urbanism
This primary objective of this research is twofold: (1) development of a methodology for using the Standard Penetrating Testing (SPT) blow count to design the laterally loaded drilled shafts, and (2) development of a methodology for design of drilled shafts to stabilized unstable slopes or embankments. The research has resulted in a development of a large database containing a total of 58 lateral load test results of drilled shafts, together with SPT information of the soil at the test site. The drilled shaft sizes range from 10 ft to 90 ft in length, and 16 inch to 72 inch in diameter. Both cohesionless and cohesive soils are included in the test database. Correlations between the SPT blow count and the soil parameters needed for establishing the p-y curves for COM624 computer analysis have been developed. The established correlation for p-y curve construction would allow the COM624 computer to predict accurately the drilled shaft deflections and bending moments when subjected to lateral loads and overturning moments. Both finite element analysis and centrifuge model testing techniques have been used in the research to gain quantitative understanding of the soil arching effect between the drilled shafts in stabilizing the unstable slopes.
