Eurocode 1998-5 for the design of earth retaining structures in seismic conditions describes calculations using the Mononobe-Okabe method. This simplified quasi-static procedure is to some extent very conservative. The article describes the limits of this method and brings out the comparison using t...

Abstract This study develops a three-dimensional sliding block model for estimating average face pressure in shield tunneling, considering three distinct driving directions based on limit equilibrium theory. The sliding surfaces initiate from the horizontal planes at both tunnel sides. The geometric...

Retaining walls are usually located next to existing structures. This runs counter to the traditional theoretical presumption of semi-infinite space, making it unsuitable to continue applying Coulomb’s theory. In order to design retaining walls with narrow backfill, improving the established theory...

[Objective] During shield tunneling in water-bearing sand layers, due to abundant groundwater and high soil permeability, screw conveyors are highly prone to blowout incidents. If control measures are inadequate, serious construction safety accidents may occur. Therefore, it is essential to study a...

For reliable seismic design of earth-retaining structures, it is critical to accurately assess the magnitude and distribution of dynamic earth pressures. Over the years, numerous experimental and numerical studies have sought to clarify the complex soil–structure interactions in backfill–wall system...

To accurately investigate the stress and deformation behavior of support structures during mechanical shaft construction, this study proposes an analytical method for active earth pressure calculation based on limit equilibrium theory, incorporating both the radial variation of the circumferential s...
