TL;DR: In this paper, the existence of a potential function to define the gradient of the plastic strain increment vector was proved based on experimental evidence, and the potential function was used to compute the gradient.
Abstract: In Part I,* based on experimental evidence, the existence of a potential function to define the gradient of the plastic strain increment vector was proved. The study is continued in Part II by defi...

TL;DR: In this paper, it was shown that ice lenses in natural soil are normally formed in a thermal gradient regime, and this permits the development of an undulating frost line if a range of pore sizes exists.
Abstract: Ice lenses in natural soil are normally formed in a thermal gradient regime, and this permits the development of an undulating frost line if a range of pore sizes exists. Evidence is presented that...

TL;DR: In this paper, a number of load tests carried out on drilled cast-in-place concrete caissons are described, along with some pertinent geo-technical properties of the glacial till overburden and shale bedrock.

TL;DR: In this paper, the authors presented a strain energy hypothesis which explains the behavior of overconsolidated clays and the phenomena of long-term slope failures in these soils, and demonstrated that strain energy can explain the behaviour of clays.
Abstract: Bjerrum recently presented a strain energy hypothesis which explains qualitatively the behaviour of overconsolidated clays and the phenomena of long-term slope failures in these soils. Quantitative...

TL;DR: In this paper, it was shown that the magnitude of the heaving pressure in silt soils is governed by the geometry of the ice-water in the formation of ice lenses.
Abstract: Research on heaving pressures associated with the formation of ice lenses in soils indicates that the magnitude of the heaving pressure in silt soils is governed by the geometry of the ice-water in...

TL;DR: In this paper, two experiences with the use of a new piezometer were reported and the principle of operation was similar to the Geonor Piezometer in that water permeates through a porous membrane.

TL;DR: In this paper, the authors investigated the performance of elephants as compactors of irrigation canal embankments and found that no record of elephant's performance as a compactor was discovered.
Abstract: Erosion of irrigation canal embankments during the wet season is a perennial problem in Northeast Thailand. Grass cover is often difficult to establish because, among other reasons, the embankments are convenient pedestrial thoroughfares. Proper compaction of the embankments is an obvious remedy but is seldom applied for lack of suitable compaction equipment. Maintenance of embankments had become a major problem along the main canal. It occurred to the frustrated field engineers that local unemployed elephants might be recruited at a resonable rate to perform the compaction. Although several opinions were offered on the efficacy of such a means, no record of the performance of elephants as compactors was discovered. Accordingly, it was decided to resolve this question by undertaking a modest field investigation.... Language: en
