3D Finite Element Analysis of a Contiguous Pile Wall

The development site is located on sloping ground approximately 35 m from a motorway cutting. Due to the sloping topography of the site, cut and fill earthworks are to be undertaken to form a level development plateau upon which a large warehouse is to be built. This will require the construction of a circa 400 m long contiguous pile retaining wall to support the ground along the site’s upslope boundary where ground levels will be reduced by up to 8.4 m. Wall Design A plan showing the arrangement of the piles and the 2.0 m wide by 0.8 m deep capping beam is shown in Figure 1. The main 900 mm diameter piles are 17 m long and are staggered in a zigzag arrangement at 0.25 m offsets either side of the capping beam centerline. Interspersed mid-way between the main piles are 600 mm diameter infill piles. The infill piles are located along the capping beam centerline and are 11 m long. Figure 1: Pile and capping beam arrangement Ground Conditions The ground conditions are summarized in Figure 2 which shows a 2D section perpendicular to the wall alignment at the location where the retained height attains its maximum value of 8.4 m. The succession of strata comprises a veneer of clay-rich Glacial Till overlying Coal Measures bedrock. The Coal Measures bedrock is dominated by siltstone and mudstone and has been divided into three [...]

Geotechnical Experts on site Today Developing a Plan at Wildcat Creek Bridge

August 8, 2015 Geotechnical Experts on site Today Developing a Plan at Wildcat Creek Bridge TIPPECANOE COUNTY, Ind. – Geotechnical experts observed conditions at the I-65 northbound bridge over Wildcat Creek today and are working to test and analyze the soils and develop a detailed plan to address and prevent further pier settlement. INDOT Commissioner Brandye Hendrickson briefed Governor Mike Pence by phone today and he is monitoring the situation. What happened Structural engineers monitoring the I-65 northbound bridge over the Wildcat Creek noticed movement in the riverbank pier and ordered the bridge closed Friday afternoon. An estimated reopening date for the bridge will not be known until soils testing and analysis is completed. INDOT will work to provide updates as new information is available. Detour I-65 northbound merges to one lane and is diverted onto U.S. 52 at Exit 141 north of Lebanon. Follow U.S. 52 north for nearly 17 miles, then turn left at State Road 28. Follow S.R. 28 west for about 10 miles, then turn right onto U.S. 231. Follow U.S. 231 north for about 33 miles until it intersects I-65 again in White County. INDOT thanks the motoring public for their patience while engineers and other experts work to safely reopen the bridge. INDOT is installing temporary traffic signals at the S.R. 28 intersections with U.S. 52 and U.S. 231. Until those are completed late on Sunday, INDOT and law enforcement staff are helping to direct traffic. INDOT engineers are monitoring traffic flow on U.S. 231 signals and adjusting timing patterns. INDOT has asked contractors to suspend work where the official detour rejoins I-65 in White County. Message alerting travelers of the closure are posted on dynamic message signs as far south as the Louisville metro area. INDOT is working to identify and clear alternate routes [...]

Alumni of CEE's Geotechnical Engineering program have made significant contributions to major projects like subway systems in the nation’s largest cities, the Hoover Dam and the World Trade Center. Today, geotechnical engineering faculty members have expertise in earthquake engineering, soil mechanics behavior, foundation engineering, rock mechanics and tunneling, and advanced numerical modeling techniques. Research interests of the Geotechnical Engineering faculty include: Deep excavations Earthquake engineering Numerical modeling Static and dynamic Soil-structure interaction. Engineering properties, construction problems, and ground modification technology in soft clays and silts, stiff clays and soft rocks, and granular materials Soil-structure interaction Reliability-based design Mechanically stabilized earth and earth support systems Ground improvement methods and their effect on structures Soil liquefaction during earthquakes The static and seismic stability of natural and excavated slopes Source: Geotechnical Engineering | Civil and Environmental Engineering at Illinois Geotechnical Engineering Illinois
