TL;DR: In this paper, the authors describe a theoretical and experimental investigation of buckling of a tube surrounded by a soil in a circular symmetric configuration and show that the tube failed by increasing the effective stress and the pore pressure acting on the tube.
Abstract: This paper describes a theoretical and experimental investigation of buckling of a tube surrounded by a soil in a circular symmetric configuration. The tube was failed by increasing the effective stress and the pore pressure acting on the tube. Results correlated well with the theory for buckling of an elastically supported tube. Further, the modulus of elastic soil support was shown to agree well with the modulus of resistance of the surrounding soil cylinder to uniform pressure applied at its inner boundary. Application of the results to practical situation indicated that the surrounding soil increases the buckling resistance of tubes by orders of magnitude over that of unsupported tubes. Hence, in reasonably stiff soil elastic buckling at stresses much below yield is a design criterion only for extremely thin-walled metal tubes.

TL;DR: In this article, a study of analyzing a waterfront retaining wall under the combined action of tsunami and earthquake forces is presented, where the stability of the wall is assessed in terms of its sliding and overturning modes of failure, and the factor of safety in sliding mode of failure decreases by about 70% when the ratio of tsunami water height to initial water height is changed from 0.375 to 1.125.

TL;DR: In this paper, the normal stresses exerted by two agricultural vehicles (a rubber tracked Caterpillar Challenger 65 and a Steiger Tiger 550 4WD tractor fitted with low pressure dual wheels) were measured with electronic earth pressure cells at four depths (150, 300, 400 and 500 mm) in a sandy soil located in the West Australian wheatbelt.
Abstract: Normal stresses exerted by two agricultural vehicles (a rubber tracked Caterpillar Challenger 65 and a Steiger Tiger 550 4WD tractor fitted with low pressure dual wheels) were measured with electronic earth pressure cells at four depths (150, 300, 400 and 500 mm) in a sandy soil located in the West Australian wheatbelt. Cone penetration resistance and dry bulk density were also measured at these depths before and after traffic treatments. Uniaxial soil compression testing was done on soil cores sampled at the 300 mm depth where the peak normal stresses were measured during vehicle passage. The Cat 65 exerted less normal stress on the soil than the Steiger 550 at 400 and 500 mm depth. However, the soil had a higher penetration resistance after the passage of the Cat 65 relative to the Steiger 550. Profiles of cone penetration resistance were more discriminating in distinguishing soil physical changes among the trafficked and untrafficked treatments than dry bulk density and most of the parameters derived from compression tests.

TL;DR: The finite element method was designed to solve soil-pile-structure interaction under seismic excitation by introducing "solid beam elements" to reproduce beam flexure and soilpile interaction as discussed by the authors.
Abstract: The finite element method was designed to solve soil-pile-structure interaction under seismic excitation by introducing "solid beam elements" to reproduce beam flexure and soil-pile interaction. Dynamic lateral load-deflection relationships were characterized by ratio of soil reaction per unit pile length to product of pile displacement relative to free-field motion and dynamic stress-strain properties of soil. Three hetergeneous soil profiles with equivalent linear approximation of nonlinear stress-strain behavior were used with this new finite element method to study the characteristics of dynamic lateral load-deflection relationships. Results were compared with those by other investigators and showed that the proposed method provided improved means of evaluating load-deflection relationships of piles. Results of this study were used to compute discrete soil-pile springs and dashpots for use in a beam-on-Winkler foundation model. (ASCE)
