Soil beds of high-rise buildings

Methods employed to investigate and determine design parameters of the soil beds of high-rise buildings are examined.     

Prediction of the stress state in a soil mass of limited thickness and width under local loading

Expressions in the form of series are derived for determination of the stress distribution in a given soil mass of limited thickness and width under a uniformly distributed load and a load varying sinusoidally for the case of the plane problem. The stress state is compared between soil masses of different thicknesses and widths and a soil mass in the form of a half-space. It is demonstrated that they converge with increasing layer thickness and width of the soil mass. Translated from Osnovaniya, Fundamenty i Mekhanika Gruntov, No. 3, pp. 2–5, May–June, 1996.     

Interaction between pile foundation and soil

Problems of interaction between a single long pile (more than 20 m) or a group of long piles as component parts of a pile foundation and soil are discussed on the basis of a new geomechanical model. The settlement of a pile or group of piles is caused primarily by shear deformations of a soil mass of limited area and depth, and also as a result of deformations of the mass beneath the lower ends of the piles. __________ Translated from Osnovaniya, Fundamenty i Mekhanika Gruntov, No. 2, pp. 2–7, March–April, 2007.     

Stress-Strain State of Weak Saturated Clay Beds of Embankments

Results are presented for laboratory and field tests of weak saturated soils serving as beds for embankments in Ho Chi Min City and various regions of the Mekong River Delta (Vietnam). A method is outlined for quantitative evaluation of the stress-strain state (SSS) of the weak saturated clayey beds (plane problem). A method is described for quantitative evaluation of the deformation and stability of weak beds in the initial, intermediate, and stabilized stages of the formation and transformation of the SSS. __________ Translated from Osnovaniya, Fundamenty i Mekhanika Gruntov, No. 5, pp. 2–6, September–October, 2005.
