Consideration and review of the stochastic medium theory for predicting the settlement of the surface ground

2011 International Conference on Consumer Electronics, Communications and Networks (CECNet), 2011
Through the development of the stochastic medium theory for predicting the settlement of the surface ground due to construction of underground engineerings, analyze deformation mechanism of soils is based on the stochastic medium theory. By establish the mathematical model of soil unit, providing the calculate formulas of predicting the settlement of ...

Stochastic geometrical diffraction theory in a random medium with inhomogeneous background

Optics Letters, 1987
The recently formulated stochastic geometrical theory of diffraction is here applied to reflection, transmission, and diffraction of the high-frequency two-point coherence function when interfaces or scatterers are embedded in a randomly fluctuating medium with inhomogeneous background. This extends the previous solutions for a homogeneous background.

Modeling of tunneling-induced ground surface movements using stochastic medium theory

Tunnelling and Underground Space Technology, 2004
Abstract Tunneling-induced ground surface movements were modeled using the stochastic medium theory. The formulated ground movement equations were coded in a computer program, which was then used to perform back analyses of 18 ground surface settlement profiles available in the literature.

Analysis of Ground Movement in Pile Driving Based on Stochastic Medium Theory

Applied Mechanics and Materials, 2013
In order to calculate the ground movement induced by displacement piles driven into horizontal layered soil, it is simplified to an axisymmetric problem. Then the vertical and horizontal ground movement functions were deduced based on stochastic medium theory.

Soil deformation induced by Double-O-Tube shield tunneling with rolling based on stochastic medium theory

Tunnelling and Underground Space Technology, 2016
Abstract The prediction of soil deformation during tunneling is very difficult for Double-O-Tube (DOT) shield tunnel construction, especially for the shield rolling. According to the characteristics of DOT shield tunneling and rolling, a calculation model of soil deformation due to tunneling-induced ground loss was established.

Prediction of Ground Settlement Due to Excavation of a Quasi-Rectangular Shield Tunnel Based on Stochastic Medium Theory

Geotechnical and Geological Engineering, 2019
In this study, a method for calculating the ground loss-induced ground settlement during quasi-rectangular shield (QRS) tunnelling was investigated. Based on stochastic medium theory, an equation for calculating QRS tunnelling-induced transverse ground settlement was derived. A tunnelling face convergence mode coefficient, α, was introduced to make the

Stochastic theory of waves and localization in two-dimensional random medium

Radio Science, 2002
Random wave field satisfying two‐dimensional (2D) wave equation with a random medium is studied using the stochastic representation in the polar coordinate system. The random medium is assumed to be a homogeneous and isotropic Gaussian random field, and its polar spectral representation is effectively employed in the method of solution. The isotropy of
