3D Finite Element Analysis of a Deep Excavation & Ground Response Evaluation

July 28, 2022 Rocscience Comments Off on 3D Finite Element Analysis of a Deep Excavation & Ground Response Evaluation

How do you analyze a 43 m deep high-rise basement excavation adjacent to a highway and a railway where you have a combination of cantilevered concrete pile wall, ground anchors, and a vertical rock cut and rock buttress? You use Rocscience’s RS3 finite element software and the observational approach! […]

How Could a Pile of Dirt Cause a Major Interstate Bridge To Tilt?

October 20, 2015 Dennis M. O'Shea Comments Off on How Could a Pile of Dirt Cause a Major Interstate Bridge To Tilt?

On June 2, 2014, the Delaware Department of Transportation closed a bridge on I–495 that was leaning and out of plumb.[Editor] The Delaware Department of Transportation (DelDOT) had a major problem on their hands after a bridge on I-495 was leaning…one side of the bridge was 18 inches higher than the other.  The culprit?  A pile of fill adjacent to the bridge was loading soft soils beneath.  So what do you do about it?  In this contributed article by Dennis M. O’Shea, bridge engineer in the FHWA Delaware Division Office, he describes the problems faced by DelDOT, the causes, and how they fixed it.  The article originally appeared in Public Roads Magazine, and is republished here with permission.

Historic Brewery Restored With Help of Geopolymer

July 13, 2015 Ty Taylor Comments Off on Historic Brewery Restored With Help of Geopolymer

Historic Pearl Brewery in downtown San AntonioTurning a 119 year old brewhouse into a four-star boutique hotel is no easy task. For the project to be a success, the structure had to literally be raised from it’s grave.

Pearl Brewery operated from 1883 until 2001 in their downtown San Antonio, Texas location. It was once the largest brewery in Texas, and even kept afloat during the Prohibition era. Today the 22- acre Pearl site grounds has become a culinary gathering place where you can eat, live, learn, and play on the banks of the San Antonio River.

Renovating the original building would be no easy task for the developer. The building had settled approximately 5 inches.  URETEK ICR successfully used their patented URETEK Method® to lift and stabilize the foundation with geopolymer.

Maine Bridge Uses First GRS Wall in a Marine Environment

June 5, 2015 Lindsey Manthei O'Connor Comments Off on Maine Bridge Uses First GRS Wall in a Marine Environment

This GRS-IBS solution is the first in a marine environment.The City of North Haven is located on an island off the coast of Maine. This town was faced with a unique challenge when a bridge needed replacing. Looking for an economical option, designers decided on a Geosynthetic Reinforced Soil – Integrated Bridge System (GRS-IBS). This solution allowed the town and DOT to re-use an existing bridge pier, beat the construction deadlines, and provide a modern bridge solution for this small town.

Pond Embankment Stabilization with Geopolymer Injection

December 10, 2014 Ty Taylor Comments Off on Pond Embankment Stabilization with Geopolymer Injection

 

Geopolymer injection to sto seepage[Editor] An effluent pond in southeast Texas was suffering from years of erosion.  Recently, an escalation of subsurface water seepage through the pond’s embankment threatened the community’s main water source. URETEK used their versatile geopolymer product to inject beneath the embankment to seal off the seepage.  The project was a huge success!
