Geogrid Reinforced Soil Abutments in High Seismic Environments – Case Study from New Zealand

Load bearing geogrid reinforced soil (GRS) abutments are becoming an economic and popular solution for supporting single-span bridges on major transportation projects in New Zealand, particularly where shallow ground provides adequate bearing capacity. While their use has been pioneered in low-seismicity regions usin...

Use of soil reinforced with geogrids under shallow foundations for enhanced performance

In many cases engineers have precautions when they plan and execute a traditional subsoil excavation and substitution for better compacted selected soil. However, in the author’s practical experience frequently they tend to miss the focus about the zone of influence of the bearing pressure underneath foundations, someti...

A FIELD-CALIBRATED NUMERICAL–EMPIRICAL FRAMEWORK FOR DEEP EXCAVATION DESIGN IN SOFT ALLUVIAL SOILS OF İZMIR, TÜRKIYE

In densely populated urban environments, deep excavations in soft ground present critical geotechnical challenges due to high groundwater table and weak cohesive soils. Diaphragm walls supported by struts or tieback anchors are frequently used to stabilize such excavations, yet predicting deformation behavior remains c...

A Review of Rock Socket Skin Friction for Cast In-situ Bored Piles based on Instrumented Pile Load Tests

With rapid societal development, there is an increasing trend of communities establishing settlements near townships to meet socio-economic needs. However, due to the scarcity of available lands for infrastructure and community development, low-lying marshy lands are often encroached upon. Constructing structures on th...

Experiences in the design and construction of true abutments in areas of high seismicity

The use of mechanically stabilized soil retaining structures has been booming in recent years in Central America, especially in road structures. One of less used uses and more specialized is as a true abutment in bridges, where geometry and loads must be analysed with special attention. During the last 20 years we have...
