From:Canadian Journal of Civil Engineering (Vol. 43, Issue 11) Peer-ReviewedThe permanent deformation of the road subgrade soil accumulated during passage of the cyclic loads is mainly due to the post-compacting and plastic flow mechanisms according to a study by the National Cooperative...

From:Soil Research (Vol. 55, Issue 8) Peer-ReviewedThe evolution of the behaviour of kaolinite-smectite mixtures was studied using mechanical and electrokinetic tests. Oedometric tests showed that the compression index of the mixtures increases with increasing smectite...

From:Canadian Geotechnical Journal (Vol. 53, Issue 12) Peer-ReviewedDispersive clays experience deflocculation in the presence of somewhat clean still water and are extremely vulnerable to erosion. Lime or Portland cement usage is one of the most applied methods to amend such adverse...

3D cross-hole resistivity tomography to monitor water percolation during irrigation on cracking soil
Irrigation water entering soil cracks can quickly move past the root-zone without being utilised by plants. To assess the efficiency of irrigation practices, reliable methods to monitor water percolation are needed.... -
From:PLoS ONE (Vol. 16, Issue 12) Peer-ReviewedQuaternary Red Clay (QRC) is the most common planting soil with low soil fertility and low crop yields in Southeast China, with low soil fertility and low crop yields. Many factors can impact the fertility and...

From:Canadian Geotechnical Journal (Vol. 47, Issue 7) Peer-ReviewedMany geotechnical processes related to offshore foundations and pipelines on clay soils involve intermittent episodes of remoulding and reconsolidation. To assess the resulting response, it is necessary to predict the...

From:Australian Journal of Soil Research (Vol. 46, Issue 8) Peer-ReviewedThe fate of nitrogen (N) applied in biosolids was investigated in a forage production system on an alluvial clay loam soil in south-eastern Queensland, Australia. Biosolids were applied in October 2002 at rates of 6,...

From:Science (Vol. 225) Peer-ReviewedAlthough interstratified clays, which are common in soilds (1) and sediments (2), have been widely studied by x-ray diffraction (XRD), their actual physcial nature remains uncertain. Conventional theory egards theses...
-
From:Australian Journal of Soil Research (Vol. 41, Issue 5) Peer-ReviewedWe measured the volumetric water content (using neutron moisture meters) and height changes (using rods fixed in the soil at different depths) of several soil layers during swelling or shrinking of a heavy clay soil in...
-
From:PeerJ (Vol. 9) Peer-ReviewedBackground In semiarid areas, low productivity of crops has been attributed to lack of appropriate soil moisture conservation practices since droughts and soil erosion are rampant in most areas of this region....
-
From:Canadian Geotechnical Journal (Vol. 49, Issue 2) Peer-ReviewedThis paper presents an integrated bearing capacity-settlement approach to the design of shallow foundations on heavily overconsolidated clays by alterations of the "modified Cam clay" (MCC) model. The bearing capacity...
-
From:Australian Journal of Soil Research (Vol. 39, Issue 3) Peer-ReviewedAggregate coalescence in irrigated cracking clays constrains crop yields, yet little is known about it or how it can be managed. A measure of coalescence is introduced to separate the effects of natural aggregate-bed...
-
From:Canadian Geotechnical Journal (Vol. 47, Issue 3) Peer-ReviewedThis paper presents a method of analysis of the behaviour of piled rafts in clayey soils, in which a deep excavation was necessary for buildings with two or more basements. In these cases, the piled raft foundations are...
-
From:The Baltic Journal of Road and Bridge Engineering (Vol. 9, Issue 3) Peer-ReviewedFiltration properties of clay (Kuksa mine, Lithuania) were investigated and analysis of the results was done. Investigations were carried out using a permeameter with a varying hydraulic head. A potential dependence of...

From:Ground Water (Vol. 36, Issue 3) Peer-ReviewedA study was conducted to examine the preferential flow and transport of the agricultural chemicals nitrate and bromide in claypan soil at the Missouri Management Systems Evaluation Area in Missouri. Findings revealed...
-
From:Canadian Geotechnical Journal (Vol. 46, Issue 2) Peer-ReviewedSoil structures are often comprised or supported by soils that are mixtures of cohesive and granular geomaterials. These soils are termed as intermediate or mixed soils and are widely found in natural deposits and...
-
From:Canadian Geotechnical Journal (Vol. 54, Issue 2) Peer-ReviewedA mechanical approach for unsaturated expansive soils considering double porosity has been developed based on the porous media theory. In this approach, the adsorbed and the capillary water, as well as the micropores...
-
From:Soil Research (Vol. 49, Issue 1) Peer-ReviewedRunoff, soil loss, and nutrient loss were assessed on a Red Ferrosol in tropical Australia over 3 years. The experiment was conducted using bounded, 100-[m.sup.2] field plots cropped to peanuts, maize, or grass. A bare...
-
From:Canadian Journal of Civil Engineering (Vol. 34, Issue 5) Peer-ReviewedAbstract: Asbestos cement (AC) water mains were installed extensively in North America, Europe, and Australia from the late 1920s to the early 1980s and still form a significant component of water distribution networks...

From:Canadian Geotechnical Journal (Vol. 56, Issue 5) Peer-ReviewedEstimation of the bearing capacity of shallow foundations on layered soil profiles, such as a sand layer of finite thickness over clay, is mainly based on empirical models resulting from the interpretation of...
