Development of a Soil-Specific Liquefaction Assessment Framework: Role of Soil Gradation

2016/17-2019/20 • $92,000 • PI
Assessment of liquefaction susceptibility and its consequences is a major part of geotechnical earthquake engineering. The practice relies on a case-history-based relation between in-situ penetration tests and cyclic response of soils. Apart from a poorly understood fines content correction,...

Assessment of Residual Strength of Tailings Using the Cone Penetration Test and Simplified Numerical Modelling

2019/20 • $33,286 • PI
Tailings dams are massive man-made earth structures used for disposing large quantities of mining by-products, known as tailings. A great majority of the rock crushed for ore extraction does not contain sufficient amounts of desired minerals. These silt-and-sand-sized materials are mixed with...

Effects of sample and boundary imperfections on calibration of monotonic and cyclic constitutive models in sand

2018/19 • $25,000 • PI
Like many other fields of science and engineering, geotechnical engineers use laboratory testing to determine*the engineering properties of soils, so foundations, dams, tunnels and other structures can be designed and*constructed with, in, or on soils. Like all other laboratory tests, these...

Soil-specific cone penetration test interpretation framework for tailings
