  Average Material Properties of Composite Ground

  Abstract: This study discusses the average Young’s modulus arising out of the inhomogeneity and the influ-ence of the arrangements of composite materials in the ground. Numerical analysis of tunnel ex-cavation in inhomogeneous ground which distributed two material properties were carried out. In this study, the ground is composed of two types of Young’s modulus. In addition, the each volume rate of...

  Evaluation of mechanical characteristics of inhomogeneous ground by using back analysis procedure

  Abstract: This study discusses the variation of the average modulus of elasticity arising out of the inhomogeneity of ground mass. Numerical analyses of tunnel excavation in the ground with statistically distributed inhomogeneous materials are carried out. The displacements of extensometer measurements during tunnel excavation on numerical simulation were collected. Back...
