The International Journal of Geoengineering Case Histories is an official journal of the International Society for Soil Mechanics and Geotechnical Engineering, the premier scientific organization for geotechnical engineering worldwide. The Case Histories Journal covers the broad area of practice in geotechnical engineering (soils and rocks), including geotechnical earthquake engineering, environmental geotechnics and engineering geology, and energy geo-construction.
The Case Histories Journal is a peer-review journal on the geotechnical engineering practice with a focus on careful documentation of case histories with and emphasis on observations and data collected during and after project construction . Papers are reviewed by a distinguished international Editorial Board and a selected number of reviewers. All paper published in the journal are accompanied by electronic data for better documentation of each case history.
Electrical Resistivity at Internal Erosion Locations in Levees
Tucker-Kulesza, S., Rutherford, C., Bernhardt-Barry, M.
Electrical resistivity tomography
laboratory electrical resistivity
levees
sand boils
internal erosion
Internal erosion through or beneath levees frequently occurs during flood events, resulting in sand boils. Determining the extent of damage from the seepage channels that caused the sand boils remains difficult, and many sand boils are simply monitored in subsequent floods. There is a need for a non...

Geobarrier System for Protection Against Rainfall-induced Slope Failure
Rahardjo, H., Satyanaga, A., Gofar, N., Leong, E. C., Kew, J. H., Wang, C. L., Wong, J. L.

Slope failures are a common occurrence in tropical regions with a high intensity of rainfall. Tropical areas such as Singapore are normally covered with residual soils whose behaviour does not follow the principles of classical saturated soil mechanics because these soils are often unsaturated in na...

The city of Adelaide in South Australia is built on a clay plain running north-south between the Adelaide Hills and the sea. Adelaide has a Mediterranean, i.e. semi-arid, climate causing this clay to be unsaturated and stiff to very stiff when above the watertable. To improve traffic flow on the wes...

Fine Sand
Granite Chips
Finite Element
Rainfall
Rainfall-induced slope failures commonly occur within residual soil slopes. One of the possible systems for slope preventive measure is capillary barrier system. A capillary barrier is a two-layer system of distinct hydraulic properties that is used to prevent water infiltration into the soil below ...

Development of RApid REsponse (RARE) System for Motorway Bridges: Overview and Pilot Application to Attiki Odos Motorway
Anastasopoulos, I., Anastasopoulos, P., Sakellariadis, L., Agalianos, A., Kourkoulis, R., Gelagoti, F., Gazetas, G.
seismic vulnerability
real-time damage assessment
nonlinear analysis
regression models
Safety of motorway users in case of a strong seismic event is directly related to the performance of infrastructure elements, especially motorway bridges. Preventive closure until post–seismic inspection may seem as the safest option, but will unavoidably lead to severe deterioration of servic...

Frequency Based Design of KDamper for Seismic Isolation of a Single Pier Concrete Bridge
Sapountzakis, E., Syrimi, P., Antoniadis, I.
Seismic Isolation
Negative Stiffness
Bridge
Frequency Domain
KDamper
Contemporary seismic isolation systems for bridge applications provide a) horizontal isolation from earthquake shaking effects, and b) energy dissipation mechanisms to reduce displacements. Throughout the years, many kinds of seismic isolation mechanisms have been developed, with those incorporating...

This paper examines and compares the minimum horizontal acceleration that is needed to initiate uplift of the single-nave barrel vault and of the rocking frame which are the two most common masonry structural systems used to bridge a span. The paper concludes that regardless of the direction of the ...
