Research on Embankment Longitudinal Cracks Along River due to Drawdown of River Water Level
Variation of water level, traffic loads and adding a new embankment to an existing embankment induces additional stresses and deformations. Longitudinal cracks develop on the pavement of the highway along river. Based on the soft soil creep model and liquid-solid coupling theory, numerical analyses using a two-dimensional finite element method were conducted to study tensile strains and vertical settlement of embankment. The results showed that the transverse gradient change for the widened portion was up to 0.96% and exceeded the criteria of 0.5%, and the tensile strain at the depth of 2m below the surface of the embankment was more than the criteria of 0.25%.
