This case history describes the foundation design and construction for the New Mississippi River Bridge, presently under construction in St. Louis, Missouri. The 1,500 ft (457.2 m) main span of the cable-stayed bridge is supported by two delta tower pylons ...

This paper presents the results of an elastoplastic finite element back analysis of an excavation made on a saturated soft organic clay deposit in Rio de Janeiro, Brazil. The excavation was conducted as part of an urbanization program, in which artificial ...

<p>Synthetic fiber reinforced concrete has been used in shotcrete for many years. This paper discusses select project case histories from around the world. The discussion focuses on why fibers are used and explains how there are many benefits, advantages, ...

The design-build delivery system is being used to erect the landmark Christopher Bond Bridge as part of the kcICON project. The cable-stayed bridge is currently under construction and will span the Missouri River on I-29/35 in Kansas City, Missouri. The design-build ...

The location of a decline shaft portal can have far reaching implications if the geotechnical conditions are not suited for safe and cost effective excavation. Ideally the portal should be positioned in an area where the excavation requires minimal support ...

<p>The use of shotcrete in tunnelling in frozen ground will be presented for an actual<br />project. There are specific demands on the mixture of shotcrete and the construction because of the frozen ground. The basics for the design especially the safety concept ...

<p>Landslides are one of the most damaging earthquake geohazard phenomena that have created considerable socio-economic losses in the past. Therefore, it is important to find out where and in what shaking conditions landslide can occur. This paper assesses ...

This study consists of two case studies of landslides in natural slope: Lei Pue Street landslide, Hong Kong and Barabensi Landslide, Nepal. The first landslide transformed into a debris flow while the second one did not. Several numerical models (Slope/W, ...

A case history of repeated dynamic and static loading tests in Alberta on two pipe piles during dissipation of driving-induced pore pressures is presented together with three reanalyzed published case histories involving similar records.

<p>Poor geological conditions are often encountered during underground construction in urban areas. Additionally, buildings, underground infrastructures and other facilities are more densely situated along or under the streets of a city or town. Changes to ...
