Reducing Static Settlement Potential Using Prefabricated Wick Drains – A Case History, Judd J. King
International Conference on Case Histories in Geotechnical Engineering
Soft fine-grained soils subjected to heavy loads, such as those imposed by rigid structures or fill, have a high potential to consolidate over time. Depending upon subsurface conditions, soil consolidation can take many years to occur. This consolidation results in settlement, and subsequent differential settlement of the ground surface, which can have damaging consequences to structures. To reduce the potential for damage to structures due to consolidation settlement, various solutions have been devised by geoprofessionals. Such solutions include pile foundations, rigid mat/raft foundations, chemical stabilization, and over-excavation/replacement. Another method is the use of prefabricated wick drains in combination with a …

Sedimentation Behavior Of Fly Ash-Kaolinite Mixtures, Xin Kang, Xiaoyi Zhao, Bate Bate
International Conference on Case Histories in Geotechnical Engineering
The sedimentation behavior of fine grained soil is largely dependent on its pore fluid chemistry. Different ionic concentration will lead to different fabrics of soil suspension, such as dispersion, aggregation, and flocculation. The ionic concentration also influences the thickness of the Diffuse Double Layer (DDL), which leads to the change in the final sediment volumes. Besides the ionic concentration influence, adding different amount of fly ash (FA) can also cause different sedimentation behaviors. The objective of this research was to quantify the interaction between fly ash and fine grained soils by comparing the influence of ionic concentration with that of …

Seismic Bearing Capacity Of Strip Footing Resting On Reinforced Earth Bed, Apoorva Agarwal, Swami Saran, S. Mukerjee
International Conference on Case Histories in Geotechnical Engineering
With an increase in demand for construction the use of poor soils becomes imperative. Soil bearing capacity and settlement play an important role in the design of foundations. Seismicity of the site is another important parameter in the design of the foundation for a structure. Hence seismic bearing capacity of soil becomes an important component in the design. In weak soils often deep foundations are recommended on account of the low soil bearing capacity available. In poor soils, ground improvement techniques are commonly used to improve the soil bearing capacity. Reinforcing earth with geo synthetic is one such technique adopted …

International Conference on Case Histories in Geotechnical Engineering
Liquefaction is one of the most important and complex topics in geotechnical earthquake engineering. During this phenomenon, pore water pressure increases as long as it will be equal to confining stresses. Hence, the effective confining stress becomes zero and the soil will not have any shear resistance. As a result the soil mass is unstable and causes much destruction. In this research, according to information from boreholes of Tabriz Urban Train Line 2 all required parameters including total stresses, pore water pressures and effective stresses, the results according to soil type and water depth for all 53 preliminary boreholes were …

The Use Of High Strength Geosynthetics In Deep Soil Mixed Levee Foundations, Brian C. Baillie
International Conference on Case Histories in Geotechnical Engineering
The construction and design of flood protection embankment levees within coastal areas has become a focal point for infrastructure management. The levees are usually constructed over soils with very poor bearing capacity due to their proximity to flood plains. The foundation soils create issues with long-term settlement, changing the protection height and creating the need to periodically build the levee back to the design height. In order to reduce settlements and the maintenance required to preserve design height protection, a deep foundation is needed for proper long term load transfer. Deep soil mixing (DSM) has become a popular deep foundation …
