| description |
This study is aimed to evaluate the performance of a cantilever diaphragm wall earth retaining system, constructed by staged excavation. The actual performance extracted from geotechnical instrument is compared with the numerical method. The numerical method is using Soil Hardening model. The simulation of the computer analysis has been carried out using different soil stiffness parameter which have been correlated from 2000N, 2500N, 3000N and 3500N values (with N is the Standard Penetration Test values). The results obtained had been used to compare with the actual performance of the field data. From the results of the finite element analysis, the obtained lateral displacement profile is reasonably in close agreement when compared to the instrumentation profile. Thus the soil stiffness parameters ( ref E50 , ref oed E , ref ur E ) which have been used to correlate based on 3500N values are suitable for the soil at the site of Kenny Hill formation, analysed in this project. The instrumentation data and the analyses have yielded very useful information for deep basement construction in terms of the selection of the soil parameters. |
