Landslide Stabilization Along The Ohio River Using Cantilevered Stub Piers, Swaminathan Srinivasan, Jess A. Schroeder
International Conference on Case Histories in Geotechnical Engineering
Landslide activity along U.S. 50 in Cincinnati, Ohio has caused roadway damage for decades. After a necessary closure of 3 lanes due to slope movements, emergency stabilization measures were undertaken to protect the roadway by providing a “pseudo” short-term solution (target 3 to 5 years) necessitated by ODOT budget constraints. The landslide shear plane was near the top of a sloping bedrock surface as much as 50 feet below grade. “Stub Piers” were installed 40 feet downslope of the roadway shoulder. The shafts were heavily reinforced across the deep shear plane but steel reinforcing did not extend the full length …

Some Remarks On The Influence Of Deep Excavations On Neighbouring Buildings, Cătălin Căpraru, Anton Chirică
International Conference on Case Histories in Geotechnical Engineering
Increasing density of urban areas leads to building high-rise buildings with deep foundations, enabling their basements for car parking and facilities. Increasing depth of the foundation of these buildings increases also the need for more rigid earth retaining systems. Thus, generally, due to the importance of the neighboring buildings, great care has to be taken in the design process of the retaining structure and the support system of deep excavation in densely built urban areas. The paper summarizes a parametric study on a geotechnical model of a deep excavation, proper to Bucharest subsoil, Romania. The analysis of the excavation was …

International Conference on Case Histories in Geotechnical Engineering
Recently new highway, motorway and railway projects take place in many developing countries within the aggressive infrastructure investment programme of governments. In rugged topography, engineers face the challenging problems of designing safe and cost effective cuts and fills for these projects especially under seismic loading and marginal stability conditions. Overall stability mechanism and safety of the cut generally controls the design decisions for the relevant section. In addition, because of the construction width limitations, in some mechanically stabilized earth wall projects sufficient width to accommodate the strip lengths of the retaining system cannot be provided. To eliminate all these problems, …

In the observational method, gaps in the available information are filled by observations. Such observations were invaluable during the construction of a 54-story building with an 8-story underground parking deck in Charlotte, North Carolina, which required an excavation nearly 100-feet deep into rock. Cracks appeared in an adjacent brick office building by the time the north side of the excavation had reached a depth of about 40 feet. Blast-induced settlement was initially suspected. As excavation continued, some soilfilled weathered joints, seams, and fractures in the rock sidewalls were observed, and displacement of the cracks increased. Inclinometer casings were installed along …

Field Testing Of Crushed Ignimbrite For Seismic Retrofit Of Matahina Dam, Lelio H. Mejia
International Conference on Case Histories in Geotechnical Engineering
The performance of zoned embankment dams depends on the ability of filter and drain zones to prevent seepage erosion and piping of impervious materials, while providing adequate internal drainage. Because cracking of filter and drain zones might compromise their function, special care is typically exercised to build such zones of cohesionless materials that are unable to support cracks. Limited information is available on the cracking susceptibility of filter and drain materials manufactured by rock crushing. This paper presents a case history of field and laboratory testing of a crushed ignimbrite rock to evaluate its suitability as filter and drain material …

International Conference on Case Histories in Geotechnical Engineering
Highway approach embankments are often constructed over weak and compressible soils. The consolidation settlements induced by the embankment loads are known to result in downdrag forces and lateral forces on the piles supporting the bridge abutments. Several approaches are commonly employed during construction of highway bridges in Ontario in order to reduce these forces. These approaches include: preloading and surcharging to achieve the anticipated settlements prior to the installation of abutment piles; application of lightweight fill materials such as expanded polystyrene and expanded pelletized blast furnace to reduce embankment loads; and measures to expedite pore water pressure dissipation such as …
