Ground Movement Analysis Based on Stochastic Medium Theory [PDF]

The Scientific World Journal, 2014
In order to calculate the ground movement induced by displacement piles driven into horizontal layered strata, an axisymmetric model was built and then the vertical and horizontal ground movement functions were deduced using stochastic medium theory ...

A Stochastic Thermo-Mechanical Waves with Two-Temperature Theory for Electro-Magneto Semiconductor Medium

Crystals, 2023
This paper investigates an uncommon technique by using the influence of the random function (Weiner process function), on a two-temperature problem, at the free surface of the semiconducting medium, by using the photo-thermoelasticity theory.

A Random Field Theory of Electromagnetic Information [PDF]

Entropy
As a rigorous and comprehensive foundation for electromagnetic information theory (EIT), we develop a general theory that elucidates the universal stochastic structure of radiated electromagnetic (EM) fields and induced currents in generic EM information

Exact noise influenced soliton solutions of a high-order stochastic nonlinear Schrödinger equation with weak nonlocal nonlinearity in a non-Kerr medium [PDF]

Scientific Reports
In this study, a high-order stochastic nonlinear Schrödinger equation (SNLSE) with weak non-local nonlinearity in a non-Kerr law medium is investigated. This model describes the propagation of solitons in nonlinear optical fibers under stochastic effects

Improved stochastic medium theoretical model for predicting deformation of existing tunnels and strata caused by excavation of new undercrossing tunnels

Yantu gongcheng xuebao, 2023
During the construction of new tunnels undercrossing the existing tunnels, the predicted results of the stratum deformation are prone to large errors since the traditional stochastic medium theory cannot consider the influences of the existing tunnel ...

Dynamic prediction and influence factors analysis of ground surface settlement during tunnel excavation

Rock and Soil Mechanics, 2022
The construction of urban subway tunnel inevitably produces disturbance to surrounding rock and causes ground surface settlement. Dynamic prediction of ground surface settlement caused by tunnel excavation is an important method to ensure the safety of ...

Influence of Tunnel Excavation on the Deformation of a Frame Building

Buildings, 2023
Tunnel excavation inevitably causes surface deformation. In urban areas, surface deformation could lead to the deformation of surrounding buildings, which may cause damage to communities when accumulated to a certain extent.

On the question of the no symmetry of the stress tensor for open systems [PDF]

MATEC Web of Conferences, 2022
The paper discusses the influence of stress no symmetry in continuum mechanics and in stochastic processes. The no symmetry of the stress tensor arises in connection with the influence of the moment and leads to the ambiguity of the solutions of the ...
