  • Coastal Soil and Structure Behavior during Earthquake-Tsunami Multi-Hazards

    Creator:
    Qiu, Yingqing
    Abstract:
    Coastal multi-hazards, i.e., earthquakes followed by tsunamis, induce severe damage to coastal infrastructure. The multi-hazards can cause soil liquefaction, which is one of the major concerns for evaluating sediments transport potential and structure failure mechanisms. The objectives for this work is threefold. First, to build and validate a soil numerical...

  • Evaluation of ocean wave-induced liquefaction in a large scale wave flume

    Creator:
    Thielen, David Leo
    Abstract:
    Ocean waves propagating over cohesionless seabed deposits produce cyclic shear stresses within the deposit. Under certain conditions these stresses may cause a progressive build-up of pore pressure. Pore pressure accumulation can result in liquefaction or a substantial decrease in the effective stress with attendant large deformations of the seabed deposit....

  • Pore Water Pressure Response in Soil During Tsunami Loading : Numerical Formulation and Experimentation

    Creator:
    Abdollahi, Abbas
    Abstract:
    Tsunami loading can cause sediment instability, which can compromise the structural integrity of coastal buildings and infrastructure. To understand the process by which a tsunami can cause sediment instability, it is necessary to understand how the pore water pressure in the soil changes during tsunami loading. Tsunami run-up causes the...

  • Dynamic behavior of silty soils

    Creator:
    Sunitsakul, Jutha
    Abstract:
    The cyclic resistance of predominantly fine-grained soils has received considerable attention following ground and foundation failures at sites underlain by silt-rich soils during recent earthquakes. In several cases substantial ground deformation and reduced bearing capacity of silt soils has been attributed to excess pore pressure generation during cyclic loading. These...

  • Predicting pore pressure response in in-situ liquefaction studies using controlled blasting

    Creator:
    Eller, James Michael
    Abstract:
    Originally used as a method to densify loose soils, controlled blasting has expanded its applicability to geotechnical engineering by becoming a research tool to physically generate liquefaction for full-scale in-situ tests, ranging from seismic performance of deep foundations to evaluating ground improvement techniques. Current methods used to design the blasting...
