Peat Soil Consolidation

determination of consolidation time, the first thing we need to know is the consolidation coefficient value and this value may be obtained from Oedometer Test. It was expected that the value of settlement is high since peat is very soft and easily compressed. The study of the long term consolidation of peat soil is important to predict the ...

    Some scholars also propose that the consolidation process of peat soil is three-stage or four-stage consolidation. In order to describe the consolidation process of peat soil accurately, this paper focuses on the peaty soil with high organic content in Dali, Yunnan Province, China.

  • Rowe cell testing to determine peat soil consolidation ... Rowe cell testing to determine peat soil consolidation ...

    Jan 01, 2020 Peat soils are characterized by their strong low shear, high water content, large traction, and low carrying capacity. Many constructions that are built on peat soil experienced a ground settlement problem over a long period of time. To better understand this phenomenon, a consolidation testing will be made using rowe cell testing system.

    The investigation involved a series of single increment vertical consolidation and permeability tests on 250 mm diameter by 75 mm thick undisturbed samples of the peat. The increments were maintained for up to 3 years, to define the long-term secondary compression behaviour.

    Jul 02, 2021 Several attempts have been made to characterize and stabilize peat soil to make construction viable. This study encapsulates an extensive literature review of the available published data for Atterberg limits, consolidation, and stabilization of peat soil using traditional additives, especially cement and lime.

  • SHEAR STRENGTH IMPROVEMENT OF PEAT SOIL DUE TO CONSOLIDATION SHEAR STRENGTH IMPROVEMENT OF PEAT SOIL DUE TO CONSOLIDATION

    One major problem related to construction on peat deposit is the low shear strength of the soil. However previous researches have shown that the shear strength could increase significantly upon consolidation and hence some improvement methods have been developed to increase the bearing capacity of the peat deposit by utilizing consolidation pressure.

  • A Review on Hydraulic Conductivity and Compressibility of Peat A Review on Hydraulic Conductivity and Compressibility of Peat

    Further examination of the soil fabric under a consolidation pressure indicated that there was little visual difference between the natural fabric and the fabric compressed under 7000 kPa (Landva and Pheeney, 1980).Clearly, there is not much void spaces observed from the micrographs in Fig. 4a and b and that gives a clear indication that amorphous peat has a lower hydraulic conductivity if ...

    The type of soil used in this area is peat soils. The method is use two tool and then comparison. From the results of the research implication the value of soil ability (Cc) and the coefficient of speed consolidation (Cv). In testing with rowe cell, the average soil Cc value was 0.499 and the Cv value was 256.89 cm2 per minute.
