The stress-distribution angle is an important parameter for the design of retaining walls and foundation beds has a non-negligible role in rationality engineering design. There lack research on stress distribution reinforced earth-retaining under cyclic loading. In order to study characteristics geogrid-reinforced soil-retaining (GRSW) loading, GRSW different number load cycles were analyzed by...

Thermo-active structures exchange heat with the ground to provide thermal energy buildings. Consequently, is subjected changes in temperature, inducing thermo-hydro-mechanical (THM) interactions within soil. To insights into origin and manifestations of main mechanisms taking place complex fully THM-coupled finite element (FE) analyses, simple, one-dimensional problems are firstly analysed this...

In this paper, the problem of a retaining wall under active translation mode is investigated numerically. To this end, a series of numerical models is conducted using the discrete element code, PFC2D. The backfill soil is simulated by an assembly of separate cohesionless circular particles. Backfill soil was prepared by pouring soil particles from a specific height under gravity force and givin...

Objective and Scope of Project The objective of this project was to develop recommendations for compaction of cohesionless soils used as backfill materials. The Texas Department of Transportation (TxDOT) utilizes a number of sources of cohesionless soils as fill materials for embankment construction and as backfill for mechanically stabilized earth (MSE) walls. Some problems have been experienc...
