TL;DR: In this article, a geosynthetic-reinforced backfill is proposed to reinforce the backfill of a conventional integral bridge with reinforcement that is firmly connected to the full-height rigid facings.

TL;DR: In this paper, the effects of the intermediate loading histories, with and without large stress-amplitude unload/reload cycles, on the stress-strain properties of compacted cement-mixed well-graded gravelly soil, particularly the peak strength, were evaluated in multiple-step loading (ML) drained TC tests using a single specimen.

TL;DR: In this article, the results from a series of shaking-table tests on small-scale models of the following bridge types were analysed within the framework of the single-degree-of-freedom theory.

TL;DR: In this article, a series of drained triaxial compression (TC) tests were performed on two types of well-graded gravels and axial and lateral strains were measured locally on the lateral surface of solid cylindrical specimens.

TL;DR: In this paper, a series of shaking table tests was conducted using slope models with various inclinations, and the results of the analyses were used to propose a method for evaluating the stability of rock slopes.
