the consolidation test method proposed by terzaghi and used in most soil mechanic laboratories has limitations and weaknesses. to get correct results, improvement and modification of the test method is essential. several experimental methods, such as constant loading rate, gradient and constant rate of strain (crs) have been used over the past 40 years. of these methods, crs is more advantageou...

Magnetic resonance imaging (MRI) offers the opportunity to study biological tissues and processes in a non-disruptive manner. The technique shows promise for the study of the load-bearing performance (consolidation) of articular cartilage and changes in articular cartilage accompanying osteoarthritis. Consolidation of articular cartilage involves the recording of two transient characteristics: ...

In this study the characteristics and extent of the smear zone are investigated using a large, undisturbed sample. The aim of using such a sample is to capture the realistic characteristics of the smear zone in relation to the in situ soil structure during the installation of prefabricated vertical drains (PVDs) using a mandrel. The extent of the smear zone for Bulli clay (New South Wales, Aust...

This study delves into the effects of sample height on consolidation behaviour, utilising automatic air pressure consolidometer. Extensive tests were conducted three varieties dredged silt samples varying heights from Qianwan, Shenzhen, China. The salient findings can be summarised as follows: (1) Compression curves for different dimensions transitioned through distinct phases: minimal load dis...

Abstract The effect of contamination with petroleum substances (A1 jet fuel and 15W40 mineral oil) on the compressibility consolidation mixtures ice-dammed clay aeolian sand was determined in a Barden–Rowe consolidometer adapted for liquid-phase tests. deterioration filtration capacity contaminated soil medium relative to non-contamination condition is reflected by mobilization higher values po...

In this study, the smear zone due to vertical drain installation is studied using a large, in situ sample to capture the realistic characteristics of the smear zone in relation to the in situ soil structure. The smear zone extent for Bulli clay (New South Wales, Australia) is quantified on the basis of normalised permeability and the reduction in the water content prior to consolidation. The pe...
