When investigating the bearing capacity of pile foundations in danger of buckling, information on the time-dependent resistance of the surrounding soft viscous soils is essential. The aim of TUM’s research project was the examination of the lateral support of the viscous soft soil against a pile foundation. To take into account the effects of time, TUM are examining the implications of the flow of pore water and soil viscosity on the consolidation of the soil.

When performing bender element tests, good contact or ‘coupling’ with the soil is critical to obtaining clear results. On a soil sample, the element can either be pushed in, as in the case for soft clay, or created around the element itself for samples such as sand. Performing bender element tests on rocks however can create a problem, because it is not obvious how to insert the element.

Triaxial testing is a fundamental service that Trilab offer their clients. Trilab's laboratories house a total of 18 triaxial frames, which cater for specimen diameters of 50, 63, 75, 85 and 100 mm. Read why Trilab (A commercial testing company based in Australia) use GDS's high pressure triaxial cells in their labs.
