Abstract

In evaluating the stability of underground structures and designing prevention methods against the lateral flow, it is necessary to predict the amount and the distribution of the lateral earth pressure acting on these retaining structures. However, because the lateral deformation of real ground is a very complex phenomenon influenced by interaction between volumetric deformation bringing an increase of stability of ground and shear deformation causing failure of ground, any appropriate methods for estimating the lateral earth pressure in consideration of the geotechnical properties of ground and the construction conditions in embankment have not been developed as yet. Therefore, a prediction method, which considers effects of a construction speed of embankment, using the Boussinesq's solution based on the elasticity theory without using complex numerical analyses such as finite element analyses is proposed in this research.
