Secondary Compression of Organic Soils
Soils and Foundations, 1975 ABSTRACT This paper reports a fundamental study of the characteristics of secondary compression of organic soils by using an oedometer and a triaxial consolidation apparatus. Firstly, the expression of coefficient of consolidation in which secondary compression can be taken is proposed as well as a method of estimation of final settlement including ...

Influence of Structure and Liquid Limit on the Secondary Compressibility of Soft Soils
Journal of Marine Science and Engineering, 2020 The macroscopic mechanical properties of natural sedimentary soft soils, which are usually linked to their microstructure, are different from those of remolded soils.

Regression Analysis of Soil Compressibility
Soils and Foundations, 1976 ABSTRACT Statistical techniques are used to analyze and evaluate experimental data from more than 700 consolidation tests on a large variety of undisturbed soils, and regression equations are developed to estimate the compression index and the compression ratio from classification or index data. These regression equations are then examined within the

Advances in Civil Engineering, 2021 Most of the research studies on the improvement of expansive soils are focused on reducing their expansive properties; however, there are few studies on the impact of the soil compressibility after the improvement.

Buildings, 2023 The confined compression test is the most widely used test to study the compressive deformation of soil in a laboratory, and the height–diameter (H/D) ratio has a significant effect on the confined compression test results.

Compression behaviour of hydrate bearing carbonate sand - fines mixtures [PDF]
E3S Web of Conferences, 2020 High gas hydrate content has been found in fine-grained sediments containing substantial amount of foraminifera in the South China sea. One of the possible hydrate accumulation habits is filling the intra- particle voids in the foraminifera.

DYNAMIC OF PRESSURE-DEFORMATION CURVE IN UNIAXIAL COMPRESSION TEST IN DIFFERENT LOAD TIMES [PDF]
Engenharia Agrícola, 2017 : The loading application time by machinery tires and agricultural tires is one of the factors of soil compaction. We evaluated the effect of loading reduction time in uniaxial compression test, in laboratory, in some physical and mechanical parameters ...

Soil compaction by wheeling: changes in soil suction caused by compression [PDF]
European Journal of Soil Science, 2010 Soil compaction caused by agricultural machinery has been increasingly recognized as a considerable problem facing intensive agriculture. Most of the models used to estimate soil deformation during the passage of machines are based on the concept of total stress: they have neglected an important stress variable for unsaturated ...
