What is stability number ?

Taylor proposed an analyzing method to find the stability of slope with the possible greatest angle of slope and angle of internal friction. This method represents the result using a theoretical number, which is called the stability number.

How to Calculate Stability Number for Failure on the Slope With Seepage of Water?

Stability Number for Failure on the Slope With Seepage of Water calculator uses Stability number=(cos(Slope of ground))^2*(tan(Slope of ground)-((Buoyant unit weight*tan(Angle of internal friction))/Saturated unit weight)) to calculate the Stability number, The Stability Number for Failure on the Slope With Seepage of Water formula is defined as a theoretical number given by taylor to find out stability of slopes. Stability number and is denoted by N symbol.

How to calculate Stability Number for Failure on the Slope With Seepage of Water using this online calculator? To use this online calculator for Stability Number for Failure on the Slope With Seepage of Water, enter Slope of ground (i), Buoyant unit weight b), Angle of internal friction (φ) and Saturated unit weight sat) and hit the calculate button. Here is how the Stability Number for Failure on the Slope With Seepage of Water calculation can be explained with given input values -> -0.227244 = (cos(0.3490658503988))^2*(tan(0.3490658503988)-((0.006*tan(0.802851455917241))/0.01)).

FAQ

What is Stability Number for Failure on the Slope With Seepage of Water?
The Stability Number for Failure on the Slope With Seepage of Water formula is defined as a theoretical number given by taylor to find out stability of slopes and is represented as N=(cos(i))^2*(tan(i)-((γb*tan(φ))/γsat)) or Stability number=(cos(Slope of ground))^2*(tan(Slope of ground)-((Buoyant unit weight*tan(Angle of internal friction))/Saturated unit weight)). Slope of ground surface is the rise or fall of the land surface, Buoyant unit weight is the effective mass per unit volume when the soil is submerged below standing water or below the ground water table, Angle of internal friction is the angle measured between the normal force and resultant force and Saturated unit weight is equal to the bulk density when the total voids is filled up with water.
How to calculate Stability Number for Failure on the Slope With Seepage of Water?
The Stability Number for Failure on the Slope With Seepage of Water formula is defined as a theoretical number given by taylor to find out stability of slopes is calculated using Stability number=(cos(Slope of ground))^2*(tan(Slope of ground)-((Buoyant unit weight*tan(Angle of internal friction))/Saturated unit weight)). To calculate Stability Number for Failure on the Slope With Seepage of Water, you need Slope of ground (i), Buoyant unit weight b), Angle of internal friction (φ) and Saturated unit weight sat). With our tool, you need to enter the respective value for Slope of ground, Buoyant unit weight, Angle of internal friction and Saturated unit weight and hit the calculate button.
