CASE HISTORY: FOUNDATIONS FOR THE NEW MISSISSIPPI RIVER BRIDGE, ST. LOUIS (2011)
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 ...

THE ALTERNATE TECHNICAL CONCEPT PROCESS FOR THE FOUNDATIONS AT THE NEW MISSISSIPPI RIVER BRIDGE, ST. LOUIS (2011)
The Massman - Traylor - Alberici team developed a redesigned foundation system for the main pylon and anchor foundations which utilizes their equipment and experience along with field load test measurements to optimize the foundations.

PEAK AND POST - PEAK SHEAR STRENGTH OF CEMENT BENTONITE (2010)
Self-hardening cement-bentontie (c-b) slurry walls were constructed as shear walls to stabilize the downstream slope of Tuttle Creek Dam near Manhattan, Kansas. The slope stabilization was required to protect the existing pressure relief well system located ...

DRILLED SHAFT FOUNDATIONS FOR THE KCICON MISSOURI RIVER BRIDGE (2009)
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 ...

SOIL INCLUSIONS IN JET GROUT COLUMNS (2009)
Jet grouting has increasingly become one of the ground improvement technologies used to address seepage concerns and to provide strength improvement of soils. The technique of jet grouting uses high pressure/velocity jet fluids to erode the existing soil and ...

STRENGTH DIFFERENCE BETWEEN CLAM-SHELL AND LONG-REACH EXCAVATOR CONSTRUCTED CEMENT-BENTONITE SELF-HARDENING SLURRY WALLS (2009)
Cement-bentonite (c-b) self-hardening slurry walls are being constructed as a seismic retrofit to stabilize the downstream slope of Tuttle Creek Dam in Manhattan, Kansas. A full-scale test program was conducted to evaluate various slurry mixes along with two ...

CASE HISTORY, MULTIPLE AXIAL STATNAMIC TESTS ON A DRILLED SHAFT EMBEDDED IN SHALE (2006)
As was the case on this project, the uncertainty of foundation performance in shale can lead to overly conservative designs, particularly with drilled shaft foundations. An extensive Statnamic axial testing program was performed to verify that the load-settlement ...
