Upper bound to bearing capacity of layered soils
Authors: Florkiewicz Antoni
Published: January 2010

An approach to the problem of flat punch indentation into the Mohr-Coulomb layered half-space has been developed, based on the kinematical approach of limit analysis. A kinematically admissible plane-strain failure mechanism for a typical two-layer system is presented. The ultimate bearing capacity for strip footings obtained from the proposed approach compares well with the experimental data available in the literature. Key words: bearing capacity, limit state analysis, layered soil, strip footings.
Limits to common toppling
Authors: Cruden D. M.
Published: January 2010

Goodman and Bray's kinematic model of common toppling can be extended to show that the maximum angle between the slope and the dip direction of the penetrative discontinuity that allows toppling depends on the friction angle of the discontinuities and the angle of the slope when the discontinuities dip into the slope. Flexural toppling can occur when the discontinuities dip in the same direction as the slope but more steeply than the slope and the angle of friction on the discontinuities. Natural examples of toppling in these extended ranges of orientations occur. Key words: toppling, discontinuity, rock slope, anaclinal, cataclinal, plagoclinal, orthoclinal, underdip.
Comparison of pile load test methods

Instrumented model piles were loaded to failure using slow-maintained-load, quick-maintained-load, and constant-rate-of-penetration methods of loading. The piles were driven in a prepared dry-sand bed. The applied load, point load, and shaft resistance were measured using load cells and strain gauges, and axial force distribution was determined. Test data indicate that all the three methods give similar ultimate load at failure. Nonetheless, out of the three methods, the slow-maintained-load method of testing piles, which seems to simulate field conditions, gives the largest settlement for the same applied load. The axial force distribution and shaft resistance along the pile were observed to be identical for all the three pile test methods. Key words: model piles, laboratory study, axial loading, test methods, sands, point load, shaft resistance, ultimate load.
Vibrations due to pile driving—a case study
Authors: Brunning D. F. , Joshi R. C.
Published: January 2010

Results of a field study in which vibrations due to pile driving were monitored are presented. The objective of this study was to determine the effects of pile driving on a buried gas pipeline. It was concluded that, at this site, the vibrations produced through pile driving were not significant enough to cause damage to the pipeline at distances greater than 1.2 m from the pile. Key words: pile driving, vibrations, granular soils, fill, field study.
