Abstract: A 10-m-deep multipropped excavation in the overconsolidated and fissured gault clay has been monitored. Unusual features of the field monitoring were to measure strut loads and earth pressures as well as wall deflections ...

Abstract: The mechanical behavior of many soils such as stiff clays depends on their current effective-stress states and stress history. For improving design and analysis of soil-structure interaction associated with deep excavations ...

Abstract: This paper describes the application of two relatively simple models: a linear elastic–perfectly plastic Mohr-Coulomb and a nonlinear “brick” model for simulating the top-down construction of a multipropped excavation in ...

Abstract: A soil-water characteristic curve defines the relationship between the soil (matric) suction and either the water content or the degree of saturation. Physically, this soil-water characteristic is a measure of the water ...

Abstract: In the last three decades, barrettes, namely, excavated rectangular piles, have been increasingly used as foundations to resist large vertical and significant horizontal loads. Empirical approaches are commonly used for ...

Abstract: Development of pile settlement (downdrag) of piles constructed in consolidating soil may lead to serious pile foundation design problems. The investigation of downdrag has attracted far less attention than the study of ...

Abstract: Development of urban cities in hilly terrain often involves the construction of high-rise buildings supported by large diameter piles on steep cut slopes. Under lateral loads, the piles may induce slope failure, particularly ...

Abstract: Excavation induces stress changes and soil movement on existing floating piled rafts and elevated pile groups. Limited investigation of the effects of deep excavations has resulted in an incomplete understanding of pile ...

Abstract: Any new tunnel excavation may damage adjacent existing tunnels in congested cities. To evaluate the impact of new tunnel construction on nearby existing tunnels, a series of three-dimensional centrifuge model tests were ...

Abstract: Deep excavations inevitably induce stress relief and soil movement, which may affect the safety and serviceability of nearby existing pile foundations. Although the effects of excavation on adjacent piles have been studied, ...
