TRB’s National Cooperative Highway Research Program (NCHRP) Report 697: Design Guidelines for Increasing the Lateral Resistance of Highway-Bridge Pile Foundations by Improving Weak Soils examines guidance for strengthening of soils to resist lateral forces on bridge pile foundations.
The report presents computational methods for assessing soil-strengthening options using finite-element analysis of single piles and pile groups and a simplified approach employing commercially available software. [Source: TRB. Image: TRB]
[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!
