This paper presents a ground improvement method using sand as material in columnar inclusion. The main focus of the study is to model the consolidation behavior of peat soil reinforced by sand columns. The effects of sand column length and column diameter were determined using numerical analysis. It was revealed that the final …

The soft soil deposits of Malaysia can be categorized into two as: a) alluvial and marine clays and b) organic soils and peat. There is also local soft-soil-like condition created due to mining waste ponds (Kaniraj and Joseph 2006).. 3.1 Alluvial and Marine Clays. Quaternary erosion, more due to climatic and sea level changes, has produced …

This paper describes the results of the effects of cement columns on the compressibility of fibrous tropical peat soils. Coefficient of consolidation, compression index, coefficient of secondary compression, and coefficient of volume compressibility were obtained by a Rowe cell test for both, untreated peat soil and peat soil treated with ...
Abstract. This paper studies the changes in the loss on ignition (LOI), total nitrogen content (TN), and strain in a one-dimensional consolidation test on peat soil. The effects of small-range ...
Based on ASTM D442-84 (1989), the peat soil had 45.032 % ash peat and 54.968 % organic content, and it was classified as High Ash Peat. The acidity of peat soil was 4 and it was classified as Highly Acidic Peat with a pH less than 4.5. Index compression (C c) of the peat soil was 0.659 and the coefficient of consolidation (C v) was 0.317 cm 2 ...
The consolidation process of peaty soil can be divided into three stages. •. The primary and secondary consolidation are mainly drainage consolidation. •. The compression caused by decomposition mainly occurs in the third stage. •. The tertiary …
At the end of the consolidation test, the water content was calculated and the oven dry weight of peat soil, W s is 13.21 g. The height of solids, H s computed from Equation 5 is about 0.47381 cm.
eBook ISBN 9780429220593. ABSTRACT. Peat represents the extreme form of soft soil. It is subject to instability, such as localized sinking and slip failure, and massive primary …
In this case, the lateral strain of the soil mass is neglected. The testing procedure to quantify the critical soil properties associated with soil consolidation is the Oedometer Test. The term "Oedometer" derives from the Ancient Greek language and means "to swell". The test is one of the most commonly conducted, and important ...
This paper studies the changes in the loss on ignition (LOI), total nitrogen content (TN), and strain in a one-dimensional consolidation test on peat soil. The effects of small-range fluctuations in the ambient temperature and changes in the sample height on the consolidation process of peat soil are proposed and verify the inhibitory effect of …
The reconstituted peat sample was used to determine the consolidation parameters since the undisturbed samples were difficult to collect. The selected sizes of soil particles passing have been ...

First, the compression of peat is much larger than that of other soils. Secondly, the creep portion of settlement plays a more significant role in …
Previous studies fail to provide consistent information on the division method of consolidation process of peat soil. Some scholars think that the consolidation process of peat soil is the same as that of common clay, which is two-stage consolidation. Some scholars also propose that the consolidation process of peat soil is three-stage or four …
The natural moisture content obtained was 657%, within the range of previously published values for peat originating from Klias, Beaufort, and Sabah [58, 59]. The organic content was valued at 96. ...
For the comparison purposed between the reconstituted peat samples, 0.425 mm recorded the lowest value of the water content compared to the reconstituted peat 1.000 mm, 2.360 mm and 3.350 mm at ...
Moreover, the compression modulus of the three consolidation stages was proposed to be used to calculate the settlement of peat soil foundations by the layered sum method. At the same time, the influence of confinement on the compression modulus of the third consolidation stage should be considered and corrected.
Areas containing peat soil are among the most... With the increase in population, there is a dearth of land suitable for infrastructure development. Due to poor engineering properties, many areas of land remain unutilized which also slows down rapid development. ... Consolidation, and Stabilization of Tropical Peat Soil Using Traditional …
Peat soil including soil type has high compression and low bearing capacity. Improvement of peat soil can be done with stabilization using cement, lime and other materials, but it can not be applied at depths below 1 meter. Effective method to improve it is preloading method. Preloading can be applied using embankment material, so it can accelerate the …
