TL;DR: In this paper, the active earth pressure of retaining wall near rock faces was calculated based on differential slice met met metamodel (DSM) based on the Coulomb and Rankine theories.

TL;DR: In this paper, the authors proposed a method to predict the lateral earth pressures on nonyielding retaining walls with geofoam inclusions, which could be applied without the known value of the compression of the inclusions.

TL;DR: A combined retaining structure (CRS) consisting of numerous piles, a concrete platform, and a gravity retaining wall was built to support a high embankment constructed on a steep slope.

TL;DR: In this article, a series of numerical pullout tests are conducted using PFC3D under special considerations of particle angularity and aperture geometry of the geogrid, and a new variable named fabric anisotropy coefficient is introduced to evaluate the inherent relationship between macroscopic strength and microscopic fabric aisotropic coefficient.

Abstract: The utility model provides a reinforced load reducing structure of a motorway high filling culvert in a mountainous area, which is composed of two side piles of the culvert, a pile beam, a reinforcement material, a broken stone hardcore and a load reducing hole, wherein the piles, the pile beam, the reinforcement material, the broken stone hardcore and the load reducing hole are formed into a load reducing system, most embankment loads are transferred to pile tops through a soil arching effect of the pile tops and a tension membrane effect of the reinforcement material, and then the embankment loads are transferred to a lower bearing layer along pile bodies. After the reinforced load reducing structure is adopted, the reinforced load reducing effect of the top of the culvert is obviously increased, and the cracking phenomenon of the top of the culvert is effectively relieved; the loads of the top of the culvert are transferred to the lower bearing layer through the pile bodies, and the cracking phenomenon of the side wall of the culvert is obviously relieved; the influence of complex geology on culvert stress and deformation characteristics is effectively reduced; the asymmetry of the culvert stress is effectively reduced, and the separating and cracking phenomenon of the top of the culvert and a wall body is avoided; and the efficiency of the reinforcement material is obviously increased.
