The evolutions of practices of seismic slope stability analysis of earth embankment/dam are discussed in this paper. The basic concepts of various methods, salient features, advantages and limitations of each of them are elucidate. Methods for both stability analysis and deformation calculation are presented. Methods for calculation of deformation of post liquefaction stage are also briefed.

We demonstrate the generation of high-brightness supercontinuum inside thuliumdoped fiber amplifier in 1950-2450nm spectral range with 1.7W output power and 32% slope efficiency, seeded by tunable 2000nm mode-locked laser and assisted by H4-H5/F4-H6 thulium transitions. OCIS codes: (320.6629) Supercontinuum generation; (160.5690) Rare-earth-doped materials; (060.4370) Nonlinear optics, fibers

We present first all-fiber unidirectional ring thulium-doped laser, based on isolator-free theta cavity configuration and fiber Bragg mirror as filtering element. Laser provides 1W output power with 30% slope efficiency, and linewidth of about 0.2nm. OCIS codes: (060.3510) Lasers, fiber; (060.2390) Fiber optics, infrared; (160.5690) Rare-earth-doped materials

Molybdenum phosphide was adopted as a new electrocatalyst for the hydrogen evolution reaction for the first time, exhibiting an excellent electrocatalytic activity with a small Tafel slope of 60 mV dec(-1), which is amongst the most active, acid-stable, earth abundant HER electrocatalysts reported to date.

We investigate the influence on mantle convection of the negative Clapeyron slope ringwoodite to perovskite and ferro-periclase mantle phase transition, which is correlated with the seismic discontinuity at 660 km depth. In particular, we focus on understanding the influence of the magnitude of the Clapeyron slope (as measured by the Phase Buoyancy parameter, P ) and the vigour of convection (a...

calculation of lateral earth pressure on retaining walls is one of the main issues in geotechnics. the upper and lower bound theorems of plasticity are used to analyze the stability of geotechnical structures include bearing capacity of foundations, lateral earth pressure on retaining walls and factor of safety of slopes. in this paper formulation of finite element limit analysis is introduced ...

One of the most important topics in geotechnical engineering is seismic analysis earth slope. In this study, a pseudo-static limit equilibrium approach applied for slope stability evaluation under earthquake loading based on Morgenstern–Price method general shape slip surface. approach, minimum factor safety corresponding to critical failure surface should be investigated and it complex optimiz...

The development of soil conservation plans and evaluation of spatially distributed erosion models require knowledge of rates of soil loss and sedimentation on different landscape elements and slope positions. Characterization of soil erosion rates and patterns within watersheds is important for the understanding of erosion processes and landscape evolution. Experimental data that show spatial t...
