alternatives being considered for an earth retention cutoff wall adjacent to a water supply reservoir include both secant pile walls and bentonite slurry walls. the ground conditions are residual soils and weathered to decomposed rock occasionally hard solid rock in very irregular profiles. we...
due to the water content in a gypsiferous soil, you should get a slightly lower resistivity than if it were completely dried out. if you are looking for thermal resistivity check the IEEE Std 442, resistivity as part of a corrosion study check ASTM D 6431 Standard Guide for Using the Direct...
coming from the lateral load on piles community, we've always seen it as pci (pounds per cubic inch)as per Terzaghi 1955. however, we really want to get it right for STAAD, the Ks="spring constant" in metric would be kN/m3 as BigH says. in rock we are using MN/m3. by the way, it is in no way...
let us know what your application is, and we can help you better. for example, the deformation modulus is fairly well established for soil-pipe interaction.
if you replace the soldier piles with jet-grouted pipe piles you can underpin the structure as part of the retaining wall.
it is important to do alternating piles as mentioned above so the jet grouted soil can harden.
in spite of the goofed up units, its a pretty good question for the forum.
it does not seem that we have resolved how the presence of the geotextile influences the bearing capacity.
i would be tempted to somehow increase the cohesion of the clay, but would like to hear from others what they have...
you'll find some recommendations for levees in DM7 and that's about it for published guidelines for linear projects.
urban areas is 1 boring per 10,000 square feet, but i'm not sure in rural areas, so go with geopave's recommendation.
su is stress dependent; therefore it is typically normalized to the effective stress of the overburden at depth of the sample. you're going to get different su for different test methods as well.
i agree with ron; you better check the geology of the soil deposit before you go making assumptions about gradation with depth; for example, a deltaic deposit will tend to have coarsening upward gradations while a lacustrine deposity will have fining upward gradations.
i'm not sure why you were provided a link to "high mobility grouting" info; if anything you need low mobility grout for filling voids as most geotechs understand. as others have commented above, more info is needed to evaluate many options and economics.
Mayne's great procedure to get influence factors ! try it in either spreadsheet or mathcad.
however, does anyone have any ideas on how to average out the different results from the center point and the corner points?
good start might be hoek & brown 1980 appendix 5; if you add a few parameters like the rock mass classification you can get c and phi.
are you looking for the laboratory c and phi?
the term "cohesion" must be a translation error of the so-called cavity expansion theory.
the Cu term you state in your original question is the numerator of the parameter Q (see geobdg's link).
so, the good news is there's only one cohesion, but it varies up to a maximum value of the lab test i...
thanks for the attachments jobarr and geobdg; this can be a very useful discussion of cohesion and how to apply laboratory test results in engineering practice. my first step would be to use the example equation for figure 16-1 and see if the proposed equation 63 gives the same answer for Cu...
