MASW este o tehnica de indagare care permite definirea profilului de velocitate

MASW este o tehnica de indagare care permite definirea profilului de velocitate a undelor verticale VS, bazat pe măsurarea undelor de suprafață realizate în corespondență cu diferiti senzori plasați pe suprafața solului. Contribuția predominantă a undelor de suprafață este dată de undele Rayleigh, care sunt transmise cu o viteză legată de rigiditatea porțiunii de teren afectată…

Soil liquefaction

Soil liquefaction describes a phenomenon whereby a saturated or partially saturated soil substantially loses strength and stiffness in response to an applied stress, usually earthquake shaking or other sudden change in stress condition, causing it to behave like a liquid. The phenomenon is most often observed in saturated, loose (low density or uncompacted), sandy soils. This…

Discrete Element Method for slope stability

Limit equilibrium methods for slope stability analysis do not, in general, satisfy the overall equilibrium conditions; they must make assumptions regarding the inclination and location of the interslice forces. An alternative slope analysis based on the discrete element method is presented to avoid these drawbacks. A slope in the present model is treated as comprised…
