(PDF) Peat Consolidation – New Approach
The problem of consolidation of soil has been widely investigated. The basic approach was given by Terzaghi who assumed soil of constant physical and mechanical parameters. In the case of peat...

(PDF) Consolidation Behavior of Peats - …
This behavior, along with the observations of peat microstructure, supports the presence of a two-level structure for peats, possibly consisting of macropores and micropores. Test results provide...
The consolidation characteristics of peat as …
F o r inorganic soils, that show small changes in permeability during consolidation, these values may be used as the average permeability; but f o r peats, which have large changes of permeability during consolidation, these values are only useful as an indication of the change in perm-eability f o r each load increment. Permeability determined by this method will be of the correct magnitude ...
Consolidation Parameters of Reconstituted Peat …
This stone presents the consolidation parameters of reconstituted peat soils with different peat soil particle sizes. The reconstituted peat sample was used to determine the consolidation parameters since the undisturbed samples were difficult to collect.

Stabilization of peat soil using locally admixture ...
The primary consolidation of fibrous peat takes place very rapidly. A ... Peat soils are rich with water content and high porosity and in most cases its deposit is shallow from two to four meter under the surface ground as (Kafer Saad at north of Nile delta) or at deep depth of about 12 meter as (Menia Sandob, Mansoura at middle north of the delta). Cement and lime are widely used as a base of ...
Deformation behaviors of peat with influence of …
10.05.2016 · It is thus important to propose an appropriate consolidation model to describe the mechanical characteristics and the deformation behavior of peat. In this paper, a consolidation model is proposed for peat under the three phase composition of this material.
Organic Soils and Peats | SpringerLink
13.06.2017 · Organic soils and peats are considered as problematic soils in relation to design parameters used by geotechnical engineers because their engineering characteristics are inferior to those of the other soft soils which make it unsuitable for construction in its natural state (den Haan and Kruse 2006).For example, further humification of the organic constituents alter the soil mechanical ...
Peat Consolidation – New Approach in: Archives …
01.06.2011 · The problem of consolidation of soil has been widely investigated. The basic approach was given by Terzaghi who assumed soil of constant physical and mechanical parameters. In the case of peat consolidation, the permeability coefficient of soil and the elasticity modulus are functions of the settlement which is an important additional factor. The model proposed here assumes varying the ...
Analytical and Numerical Modelling of One …
There is a novel value in developing an accurate numerical prediction for the vertical consolidation of stabilized peat considering the complexity of the soil treatment method. It must be noted that peat is highly problematic because it is produced from plant decomposition with extremely high organic matter.
(PDF) Fiber Effects on Compressibility of Peat
In the engineering field, peat soil was mostly known as soils that has a serious settlement with high compressibility index. By previous research, fibers in the soil were influenced in...
Peat - Wikipedia
Peat (/ p iː t /), also known as turf (/ t ɜːr f /), is an accumulation of partially decayed vegetation or organic matter.It is unique to natural areas called peatlands, bogs, mires, moors, or muskegs. The peatland ecosystem is the most efficient carbon sink on the planet, because peatland plants capture CO 2 naturally released from the peat, maintaining an equilibrium.
Compression Index - an overview | ScienceDirect …
Figure 25.7 shows the relationship between the modified secondary compression index (from back-analysis) and the natural water content for the peat, organic soil, and clay of the CKE project together with other published data. When assessing the range of values for the organic soils, one MC result of 10% was excluded from the results due to its isolated extremity.
A review of the stabilization of tropical lowland …
24.11.2013 · The principle of using the Air Curing Technique to strengthen stabilized peat is that peat soil at its natural moisture content contains sufficient water (water content from 198 to 417 %) that, when mixed with cement, a curing process takes place that causes the stabilized peat soil to gradually lose its moisture content and to become drier and harder throughout the curing period.
DETERMINATION OF COEFFICIENT OF RATE OF HORIZONTAL ...
fibrous peat soil with both vertical and horizontal drainage boundaries is subjected to a consolidation pressure, rate of excess pore water dissipation from the soil in the horizontal direction (ch) is expected to be higher than that in the vertical direction (cv). ch/cv of two is commonly used in practice for estimation of consolidation in soft clay improved by vertical drain whereas ...
Peat unit weight effects on embankment stabilization
Peat is a unique soil in that its natural unit weight is only slightly above that of water, so that its submerged unit weight approaches nil. The unit weight increases as peat consolidates under an embankment and therefore will vary in the field from a minimum beyond the toe to a maximum under the centerline. Unit weights also vary naturally and the effect for example of assuming 10.80 versus ...
Determination of Coefficient of Rate of Horizontal ...
The coefficient of fully saturated permeability for the peat soil ranges from 10 -07 to 10 -06 cm/s. The previous study indicated that the fibrous peat soil is averagely porous and has a medium...
Horizontal consolidation coefficient : Geotech
The formation of peat deposit led to a pronounced structural anisotropy in which the fibers tend to have horizontal orientation. Thus, under a consolidation pressure, water tends to flow faster from the soil in the horizontal direction than in the vertical direction. Go through stone for more insight.
