Model tests of geocell retaining structures
Rong-Her Chen,Y.M. Chiu +1 more
TL;DR: In this article, the effect of the geocells as a major material in retaining structures and the failure mechanism of the said structures under surcharge was examined on nine model geocell retaining walls, where the main variables in the tests include the height and the facing angle of the structure, the type of surcharge, and the reinforcement embedded in the two types of externally stabilized structures.

Investigation of the evolutionary process of a reinforced model slope using a fiber-optic monitoring network
TL;DR: In this article, an innovative quasi-distributed fiber-optic sensing network based on the fiber Bragg grating (FBG) technology was developed to monitor the strain distributions of the soil nails, the slope subsurface displacements, and the internal strains of soil mass, together with laser displacement transducers for surface displacement measurement.

Seismic rock slope stability charts based on limit analysis methods
TL;DR: In this paper, the finite element upper and lower bound techniques were applied to provide seismic stability charts for rock slopes, where the pseudo-static method was employed by assuming a range of the seismic coefficients.

Effect of lithology and structure on seismic response of steep slope in a shaking table test
Hanxiang Liu,Qiang Xu,Yanrong Li +2 more
TL;DR: Wang et al. as discussed by the authors carried out experiments on four rock slopes with steep angle of 60° by means of a shaking table, where recorded Wenchuan earthquake waves were scaled to excite the model slopes.

Seismic response of embankment slopes with different reinforcing measures in shaking table tests
TL;DR: In this article, a comparison was made on the seismic response among the embankment slopes with different reinforcing measures, and the results showed that the natural frequency of reinforced embankments is larger than that of unreinforced embanksments, and reinforced embanksmen are less sensitive to seismic excitation.

SIMILITUDE FOR SHAKING TABLE TESTS ON SOIL-STRUCTURE-FLUID MODEL IN 1g GRAVITATIONAL FIELD
TL;DR: In this paper, a similitude is derived for the shaking table tests on saturated soil-structure-fluid model in 1 g gravitational field, where the assumption is made upon the constitutive law of soil; i.e., the stress-strain relation is determined irrespective of the confining pressures if appropriate scaling factors are introduced for the stress and the strain for taking the effect of confining pressure into account.
