Experimental and Theoretical Investigations on Active Earth Pressure Distributions behind Rigid Retaining Walls with Narrow Backfill under a Translational Mode

, 2020
The existing earth pressure theories, such as Rankine's theory and Coulomb's theory, adopt planar slip surfaces to establish force equilibrium equations.

Evaluation of the lateral earth pressure in unsaturated soils with finite element limit analysis using second-order cone programming

, 2020
This paper aims at studying the active and passive earth pressures on the retaining structures having an unsaturated backfill. To this end, the well-established lower bound limit analysis coupled with the finite element method and the second-order cone ...

Analytical solution for the active earth pressure of cohesionless soil behind an inclined retaining wall based on the curved thin-layer element method

, 2020
In order to improve the theoretical strictness and expand the applied range of the traditional earth pressure calculation methods, a new analytical solution for the active earth pressure distribution of the cohesionless backfill soil has been established.

An analytical model of loosening earth pressure in front of tunnel face for deep-buried shield tunnels in sand

Computers and geotechnics, 2019
For deep-buried shield tunnels in sand, it is difficult to determine the loosening earth pressure in front of tunnel face due to the significant soil arching effect during excavation.

Earth pressure prediction in the chamber for earth pressure balanced shield machines

International Journal of Computer Applications in Technology, 2018
Earth pressure balanced (EPB) shield machines are large and complex mechanical systems and have been widely applied to tunnel projects. The earth pressure in the chamber is very important for EPB shield machines to avoid ground settlement and guarantee safe construction during the tunnelling process.

Three-dimensional active earth pressure under transient unsaturated flow conditions

, 2020
The active earth pressure evaluation was typically conducted assuming dry backfills and/or two-dimensional collapse mechanisms. In practice, retained slope collapse usually shows a three-dimensional (3D) feature and soils are usually unsaturated.
