Increasing the undrained shear strength of soft ground improved by vacuum consolidation
Autor: Hirochika Hayashi, Hijiri Hashimoto
Publikováno v: Proceedings of the Institution of Civil Engineers - Geotechnical Engineering. :1-16
In this paper, the use of vacuum consolidation to improve soft ground and increase its undrained shear strength (Su) is discussed. Since peat and organic clay have very low Su values, the construction of embankments and structures on these soils ofte

Strength characteristics of cement-treated soil cured under extremely low temperatures
Autor: Osamu Hatakeyama, Hirochika Hayashi, Yuichiro Kido, Hijiri Hashimoto
Publikováno v: Proceedings of the Institution of Civil Engineers - Ground Improvement. :1-11
This paper discusses the strength characteristics of cement-treated soil cured at extremely low temperatures ranging from 5°C to −20°C. To examine how extremely low curing temperatures affect the s...

Reducing the secondary consolidation of peat ground using vacuum consolidation
Autor: Hijiri Hashimoto, Osamu Hatakeyama, Hirochika Hayashi
Publikováno v: Proceedings of the Institution of Civil Engineers - Ground Improvement. 174:173-184
This paper discusses secondary consolidation of peat ground improved by vacuum consolidation method, and quantitatively presents the degree of reduction of the secondary consolidation. When an embankment is constructed for roads, river dykes or other

Shear Modulus and Damping of Peat Subjected to Overconsolidation Stress History
Autor: Osamu Hatakeyama, Hirochika Hayashi, Masahiko Yamaki, Hijiri Hashimoto
Publikováno v: Geotechnical and Geological Engineering. 38:6421-6430
This paper describes how overconsolidation affects the shear modulus at small strain (G0) for peat, as well as the strain dependence of the shear modulus (G) and the damping ratio (h) of overconsolidated peat. Hayashi et al. (Soils Found 52(2):299–

Shear Modulus and Damping Ratio for Normally Consolidated Peat and Organic Clay in Hokkaido Area
Autor: Takahiro Yamanashi, Hijiri Hashimoto, Masahiko Yamaki, Hirochika Hayashi
Publikováno v: Geotechnical and Geological Engineering. 36:3159-3171
This paper presents that the shear modulus at small strain (G0) for peat and organic clay in normally consolidated state, as well as the strain dependence of the shear modulus and the damping ratio (dynamic property). In analyzing dynamic ground beha
