Abstract
A self-supported temporary excavation method called Inclined Earth Retaining structure (IER) has been developed by improving an existing excavation method. The stability of the IER was proved with both model tests and field tests. Especially, the results of the model tests proved that the lateral displacement of a model retaining wall was significantly reduced in clay. In this study, the applicability of the IER installed in the soft clay ground is estimated by analyzing survey data collected in the construction field. The results of FE analysis show that the lateral displacement of the IER decreased by 70.9% of that of a single row, self-supported retaining wall using the same number of H-piles. Thus, using the IER method in the soft clay ground will increase the stability of the excavated ground with the effect restraining its lateral displacement. Furthermore, using Deep Cement Mixing (DCM) to the upper half embedded depth of front support is recommended as a subsidiary method of reducing the lateral displacement of IER in the soft clay ground based on FE analysis results.
