October Emerging Professionals Meeting (Sacramento)

A New Design Method for Working Platforms Stabilized by Multi-axial Geogrid

Presented by Tensar

Join us on the 3rd Wednesday of each month for our Sacramento area Emerging Professionals Meeting. All geo-professionals welcome regardless of age or experience!

Venue will rotate between the GEI office in Rancho Cordova and the North Natomas Library in Sacramento. This month the meeting will be at the North Natomas Library in Sacramento.

Presentation Synopsis:

The design of working platforms typically involves the calculation of a two-layer bearing capacity. Existing calculation models are quite empirical with imprecise input parameters while other proposed methods have tended to involve multiple design charts and been suited to either strip or circular foundations only. It has also been difficult to incorporate the benefits of geogrid in an accurate way. The recently developed “T-Value Method” defines bearing capacity simply in terms of the ratio of strengths of the two layers and can be applied to both clay and sand subgrades. It also allows realistic incorporation of the benefit of multi-axial stabilizing geogrid in terms of the enhanced shear strength of the upper granular layer. This is leading to significant cost savings due to thinner working platforms that are designed in a safe and scientifically rigorous way. The greater ductility of stabilized granular layers also provides greater assurance that the assumed failure mechanisms can be fully mobilised before strain softening in the granular layer occurs. This presentation summarizes the development of this design new method and describes some of the full-scale field tests that have been used in its validation.
