Embankment Stability - an overview | ScienceDirect Topics

The analysis incorporated ground treatments and soil reinforcement to assess the level of stability during short and long terms. Undrained strength parameters were used in the SLOPE/W analysis with a strength increase in soft soils considered to be 0.2 times the increase in effective stress as a result of soil consolidation.

(PDF) Base Stability of Circular Excavations in Soft Clay

The critical height of an open excavation is calculated by dividing four times un-drained shear strength of soil over its density. If it is required to have stable excavation in normally consolidated soft to firm clay for considerably long time, then the safety factor is specified based on the severity of the risk that imposed by major slip.

Excavations within the freeboard area should be sloped no steeper than 1V on 1.5H. 3.2. Excavation adjacent to the levees within the limits of the levee-projected slopes should be sloping no steeper than 1V on 1.5H from the bottom of the excavation. Stability analysis may be required for the deep excavations or problem foundations. 3.3.

[PDF] Undrained Stability of Braced Excavations in Clay

Jul 15, 2003 · Short-term undrained stability often controls the design of braced excavations in soft clays. This paper summarizes the formulation of numerical limit analyses that compute rigorous upper and lower bounds on the exact stability number and include anisotropic yielding, typical of K0-consolidated clays and bending failure of the wall.

An Introduction to Slope Stability and Protection

2.2.2.1 OVERSTRESSING OF THE FOUNDATION SOIL. This may occur in cohesive soils, during or immediately after embankment construction. Usually, the short-term stability of embankments on soft cohesive soils is more critical than the long-term stability, because the foundation soil will gain strength as the pore water pressure dissipates.

Jan 05, 2022 · Blasting impact load may be encountered during the construction of some pile foundation projects. Due to the effect of blasting impact, hole collapse can easily occur in the hole-forming stage of pile foundation construction. In order to prevent hole collapse, it is very necessary to evaluate the stability of a pile hole wall before pile foundation construction.
