The test indexes of physical and mechanical characteristics of the rock of the kind of granite at the fully weathered zone from the some engineering examples are analized and studied in the paper and the characterisits of engineering geology of it is described. The differences between the zones fully weathered and seriously weathered and the fully weathered zone and residual soil are also pointed out in it.
To fulfill the seepage proof demand,the non uniformity for the upper zone material of strong weathered rock and the mixed quantities,gradations and moisture contents for fully weathered rock should be well controlled ,and be fully compacted.
When the high rockfill dam with core wall is built on the fully weathered granite foundation, liable to liquefication in strong seismic area, and the materials used as seepage prevention are fully weathered granite sand and soil with low percentage of clayey grain, liable to liquefication, the dynamic stability of the dam and its foundation body is the key issue in dam design.
It is suggested that the impervious wall combined with curtain grouting should be taken as the main vertical impervious body for seepage control,and that the full use of slope wash and fully weathered zone as horizontal impervious blanket should be taken to reduce work load for seepage control.
In this article, about the uniaxial Compression tests on the whole-weathered sandstone,mudstone with in Guangan area, we can get the index of compression strength and shear strength, at the same time we can get two kinds shape of stress-strain curve and two kinds shape of sample failure, this weathered zone stress-strain relation accord with hyperbola mode general.
According to the practical material in Fuzhou, this paper evaluates the engineering behavior of whole-weathered pelitic siltatone and provides the new ways to determine bearing capacity and the value of bearing capacity in different conditions.
Buildings constructed especially in completely weathered and residual soil levels of the andesite have some geotechnical problems.
The movements took place in completely weathered andesitic, dacitic and granitic rocks as well as slope debris.
In every profile the most depleted base cation is Mg which is directly related to the weathering of chlorite which is often present at the 20-40% level in basal horizons but is often completely weathered out in E horizons.
In some cases, mottling occurs in horizons when parent material is not completely weathered.
In terms of the exactly nonzero partition, the reducible projection-system and correlation matrices, two characterizations for a rank three operator in a CSL algebra can be completely decomposed are given.
The precursor could be completely decomposed into complex oxide at temperature below 500 °C according to the TGA and DTA results.
It is shown that a gas hydrate in a pipe can be completely decomposed under the action of a microwave electromagnetic radiation whose wavelength is comparable to the thickness of this hydrate.
The concentrations determined by HPLC and GC/MS in femoral blood, liver, kidney, vitreous humor and liquor were in the comatose lethal range for propoxur (>amp;lt; 0.3-18 μg/g), whereas tetrametrin (up to 0.1 μg/g) was almost completely decomposed.
The samples were completely decomposed and high precision results were obtained for the metallic elements.
