Prediction of free field heave using C[sub]W[/sub] and C[sub]H [/sub]indices
Journal Title: Annals of Warsaw University of Life Sciences – SGGW. Land Reclamation - Year 2016, Vol 48, Issue 1
Abstract
In order to predict free heave in expansive silty clays two methods were applied: CLOD test and double-swelling methods. In both methods C[sub]W[/sub] and C[sub]H[/sub] indices are required respectively to determine the soil heave. The CW index is determined as a slope of straight line of shrinkage curve obtained with a use of CLOD test. In case of double-swelling method two oedometer tests were carried out to determine C[sub]H[/sub] index: constantvolume and consolidation-swell oedometer tests. Comparison between heave values calculated using C[sub]W[/sub] and C[sub]H[/sub] indexes indicated slight differences.
