... ABSTRACT: Numerical and field results of a reinforced embankment on soft ground constructed up to failure are compared. The first results were obtained by a model based on the finite element method and the second by pneumatic piezometers (pore pressures), horizontal profile tube and settlement...

... and monitoring practices, as well as of some of the more recent advances in these fields. Significant progress has been made in the area of soft ground tunneling over the past thirty years, partly because of advances in computer technologies. The scope of increasing difficult project conditions to be addressed...

... ABSTRACT: The test construction was performed with large-scale models of embankment and abutment to investigate the behavior of the abutment built on soft ground and the stress in the foundation. Two kinds of abutment, named Type-A without pre-load and Type-B with pre-load, were used...

... on the capping beams and soft ground were recorded and compared with theoretical analyses, based on equilibrium of semicylindrical sand arches. The field results showed reasonable agreement with the theoretical model. The comparison between the field results is also discussed in the paper. INTRODUCTION Soft...

... of dilation in the plastic region around an unlined circular tunnel in soft ground. We further consider the state of strain rate in the polar co-ordinates r, θ plane, whose origin is the center of the circular tunnel. The equations governing the distribution of velocity throughout the r, θ plane are obtained...
