WebAug 8, 2024 · Bending and failure behavior of layered cemented tailings backfill (LCTB) was investigated. • The micro crack evolution law of inclined LCTB was investigated. • The number and angle of layer have an obvious effect on the flexural strength of LCTB. • The LCTB bearing structure changes greatly when the layered angle is greater than 5°. WebConsidering the planar rupture surface, the effect of wide range of parameters like inclination of retaining wall, inclination of backfill surface, wall friction and soil friction angle, shear wave and primary wave velocity, horizontal and vertical seismic coefficients are taken into account to evaluate the seismic active force.

Backfilling: Definition & Importance of Backfilling - HPD CONSULT
WebIt suggests that the backfill engineer needs to take the stress–strain behavior of the sill mat (e.g., ductile or brittle) ... Therefore, in this study, a series of numerical models containing the inclined sill mat and surrounding rock is established, where the sill mats have the same material properties except for the stress–strain ... WebFeb 9, 2014 · A critical review of the existing pseudo-dynamic approach is provided and a new pseudo-dynamic approach is proposed based on a visco-elastic behavior of backfill overlying rigid bedrock subjected to harmonic horizontal acceleration. Considering a planar failure surface, closed form expressions for seismic active soil thrust, soil pressure … WebTerzaghi presented a graphical solution to the lateral earth pressure problem of cohesive backfill with an inclined surface. This procedure becomes tiresome for solving practical retaining wall problems because several Mohr circles need to be drawn to determine the lateral earth pressure profile. This paper presents an analytical solution to ... geology 1303 exam 1
