In this paper, two centrifugal model tests (case 1: raft foundation, case 2: 2x2 piled raft foundation) were conducted in order to evaluate the effect of ground subsidence on load sharing among piles and raft and settlement of raft and piled raft foundations. For each case, two conditions consisting of undrained (without groundwater pumping) and drained (with groundwater pumping) conditions wer...

Preloading and Prefabricated Vertical Drains (PVD) is a ground improvement technique used to increase the consolidation process of clayey soils by means of shortening the drainage path. This paper discusses a case study of a road construction where a part of road alignment goes through a low laying water logged area. Primary consolidation of soft clay will continue for longer period of time aft...

Installing stone columns in the ground is an effective improvement technique to increase the load bearing capacity and reduce the consolidation settlement of the loose or weak cohesive soils. In addition to the increase in the bearing capacity and reduction in the settlement, stone columns can accelerate the dissipation rate of the excess pore water pressure generated by the surcharge, which ex...

The expansion of underground structures is important in urban areas with high population density. In most large cities in the world, urban development is spreading along the structures. These structures are generally located at shallow depth; therefore study of shallow tunnels in urban areas is critical for development. During the excavation of tunnels in urban areas, creating the asymmetric se...

Knowledge of larval behaviours of sessile marine invertebrates from release to recruitment and of the role these behaviours play in determining adult distributions is limited. In manipulative experiments using larvae from the Great Barrier Reef sponge Rhopaloeides odorabile, we quantified larval behaviours associated with vertical migration, phototaxis and swimming ability. We also measured set...

This paper presents promising new technologies for soft ground improvement which include the low improvement ratio cement column method (LCC) and the lightweight banking method using foam mixed soil (LFS). As a measure to reduce settlement and lateral deformation due to road embankment loading on soft ground, the column type deep mixing method used at a low improvement ratio of around 10-20% th...
