## What is slope W used for?

SLOPE/W is the leading slope stability software for soil and rock slopes. SLOPE/W can effectively analyze both simple and complex problems for a variety of slip surface shapes, pore-water pressure conditions, soil properties, and loading conditions.

## What is lambda in slope W?

Another iterative solution determines the interslice force factor (lambda; the ratio of the interslice shear and interslice normal forces) generating the same factor of safety for both moment and force equilibrium. (More information on the limit equilibrium method is provided in the SLOPE/W Engineering Book.)

**What is factor of safety for slope?**

The slope stability safety factor refers to the ratio of the soil shear strength to the shear stress of a possible sliding surface in the slope.

### What is seep analysis?

SEEP/W is a powerful finite element software product for modeling groundwater flow in porous media. SEEP/W can model simple saturated steady-state problems or sophisticated saturated / unsaturated transient analyses with atmospheric coupling at the ground surface.

### What is a phreatic surface?

The phreatic surface is the water that naturally flows through an earthen dam, like Oroville Dam. To keep the dam safe, experts say the California Department of Water Resources must know with certainty how much water is coming out of the dam and where.

**What is Spencer method?**

The Spencer Method of Slices was developed by Spencer in 1967. It is one of the most theoretically rigorous Methods of Slices since it satisfies both force and moment equilibrium of the failure mass. Thus, it enables more precise calculations of the Factor of Safety (FoS).

**What is Janbu method?**

Papers by Keyword: Janbu Method The Janbu method is used in the limit equilibrium because it can meet all the equilibrium conditions, including the force and moment equilibrium equation. The Lagrangian difference method which based on shear strength reduction is adopted in numerical analysis.

#### How do you stop slope failure?

Slope failure can be improved by the plantation because the roots of the plant make the soil stable. Slope failure can be prevented by grouting (a thin and coarse layer of mortar is poured into various joints to consolidate into solid mass) which increases the stability of the soils.

#### What is slip surface?

The surface along which an earth bank is liable to fail under load.

**What is geo studio?**

GeoStudio is an integrated software suite for modeling slope stability, ground deformation, and heat and mass transfer in soil and rock.

**How do I get my GeoStudio student license?**

The Student Edition license is included for free when you download GeoStudio. You may freely distribute the Student Edition, provided you adhere to the included license agreement. This allows you to replicate it on CD and distribute it to an entire class of students.

## What is seepage rate?

Seepage velocity is the velocity of groundwater calculated from Darcy’s law. Seepage velocity is not the actual velocity of the water in the pores, but the apparent velocity through the bulk of the porous medium.

## What is pore pressure in soils?

Definition. Pore-water pressure is the pressure (isotropic normal force per unit area) exerted by the fluid phase in a porous medium (soil or rock) composed of a solid framework and pores filled or partially filled with water or other fluid.

**What is phreatic water level?**

The phreatic zone, or zone of saturation, is the part of an aquifer, below the water table, in which relatively all pores and fractures are saturated with water. Above the water table is the vadose zone.

**What is slip circle?**

The slip circle method of slices is commonly used in the analyses of slope stability and bearing capacity for multi-layered ground.

### What is Morgenstern price method?

The Morgenstern-Price (MP) method is an effective solution to compute the factor of safety (FOS) of a slope against sliding that has been used extensively for decades. In the MP method, the soil mass above the slip surface needs to be tediously divided into vertical slices to compute the force and moment integrals.

### What is stability number?

Stability number method: It is the method used to evaluate slope stability for homogeneous soils having cohesion. This method is proposed by the Taylor. It is based on the principle resistance of soil mass against sliding, because of cohesion and internal friction acting over the failure plane.
