Orientations during drained and undrained triaxial shear tests on an artificially made clayey soil were studied. The results show that the orientation pattern before shearing is nearly random, although there may be some degree of preferred orientation caused by the overburden pressure. Becoming higher ...
Rethinking the Contribution of Drained and Undrained Grasslands to Sediment-Related Water Quality Problemswater qualityGrass vegetation has been recommended for use in the prevention and control of soil erosion because of its dense sward characteristics and stabilizing effect on the soil. A general ...
The aim of this study was to determine the load of Escherichia coli transferred via drainage waters from drained and undrained pasture following a grazing period. Higher concentrations (ranging between 104 and 103 CFU g-1) of E. coli persisted in soil for up to 60 days beyond the point ...
In a recent study conducted in Ireland comparing the peak runoff rates from mole-drained and undrained plots in a field experiment on clay loam soil, however, lower peak runoff rates were measured in the undrained than in the drained treatments (Tuohy et al., 2016). Yet, it must be noted...
The concentrations of Ca, Mg, K, Fe, Mn, Al, Cu, Zn, Mo, Pb, Cr and Cd were determined for surface peat samples for 80 sites on both undrained and drained pine mires in Finland. The oldest areas had been drained 55 years earlier. Although the gravimetric concentrations of many ...
Sydney Soil Model. II: Experimental Validation The model has also been employed to simulate the drained and undrained behavior of structured clays and sands, including calcareous clay and sand. Five ... DW Airey,JP Carter,MD Liu - 《International Journal of Geomechanics》 被引量: 1发表: 2015...
2.For it′s creep behavior,undrained shear strength of saturated clay is related to load rate.由于流变特性的影响,饱和粘土的不排水抗剪强度与加载速率有关。 3.New soil classification chart and undrained shear strength ( c u) based on CPTU are developed in this paper.:孔压静探试验 (简称 CPTU...
Soil moisture and water table elevations were measured at an undrained Atlantic White Cedar swamp control site, and artificially-drained site where flashboard risers were installed in an attempt to restore wetland conditions, and an artificially-drained site with no water control structures which had...
(1998) compared ET from a drained and undrained wetlands in Indiana, where water level rarely dropped below root zone, and found no significant difference in ET due to sufficient soil moisture to sustain ET at its potential rate. Similar result was observed by Thompson et al. (1999) in ...
