Wetting Deformation

Through lots of triaxial and a single-line wetting path experiments for slaking deformation of the remolded laterite , behaviors of stress-strain and volumetric strain-axial strain are studied at different level values of wetting stress.The test results indicate that the modulus of deformation and the strength of samples are reduced by wetting, that the value of wetting deformation is relation to the stress state and that the logarithmic relationship between wetting axial strain of the type of laterite and wetting stress levels meets . The test results obtained have an important reference value for actual projects in Jiangxi laterite area.

AbstractThermoluminescence (TL) ages were obtained for five loess samples taken from the Zhaitang section near Beijing, China, using the coarse-grain quartz technique. The paleodose values have been determined by the method of total sample bleaching and regeneration of the TL growth curve. The method appears to be suitable for the age determination of loess samples up to about 150,000 yr where the annual dose-rate values are of the order 3–4 mGy/yr. This limit is a function of the total accumulated dose. The ages are in good agreement with those obtained by a fine-grain TL technique and are consistent with geological and geomagnetostratigraphic evidence.
