Modeling the internal erosion behavior of lignosulfonate treated soil

Abstract


  • This paper presents the development of an analytical model to predict the

    erosion rate of stabilised soil based on the law of conservation of energy. The model

    incorporates the strain energy intensity until failure, obtained from the stress-strain

    curves of lignosulfonate treated soil, to account for the stabilisation. The novel approach

    of this model is to correlate the shear strength characteristics with the erosion resistance.

    The proposed equation was used to predict the erosion rates of a non-plastic silty sand

    treated with lignosulfonate. The erosion resistance was interpreted in terms of the

    coefficient of soil erosion and the critical shear stress initiating erosion. It was observed

    that with the increasing amount of lignosulfonate, the critical shear stress increases and

    the coefficient of soil erosion decreases. The proposed model predicts the erosion

    resistant behaviour of lignosulfonate treated soil similar to the laboratory experiments.
