ABSTRACT: The bearing capacity of shallow foundations is classically computed as the sum of three contributions, coming from the soil cohesion, the overburden pressure and the weight of the soil mass mobilized by the collapse mechanism. Each of these contributive terms is then multiplied by several special corrective factors that account for the effect of the shape, depth and tilt of the founda...

Foundations may undergo severe distress during an earthquake. One such example of foundation failure involving toppling of apartment blocks due to liquefaction during the 1964 Niigata Earthquake is presented in Figure 1. Earthquake effects on shallow and deep foundations are accounted for by designing them structurally to provide necessary strength and ensure serviceability. Strength considerat...

We characterize the stable theories T for which the saturated models of T admit decompositions. In particular, we show that countable, shallow, stable theories with NDOP have this property.

Extensive damage to buildings and infrastructure observed during past earthquakes resulting from the liquefaction of shallow saturated soil deposits underneath structures has demonstrated necessity for further research in area liquefaction-induced ground movement effects. This study explores utilizing helical piles as a countermeasure reduce foundation settlement investigates their seismic perf...

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...
