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.

Estimation of the density state of anthropogenic soils using a dynamic heavy penetrometer (DPH)
The loading of natural and anthropogenic soils can be determined in the field by using dynamic probing tests. This method is based on the measurement of the resistance, which the studied soil poses on the probe tip when...
