11. THE STABILITY OF SLOPES analysis of deepseated failure of foundations and retaining walls. 11.4 THE φφφφ = 0 METHOD OF SLOPE STABILITY ANALYSIS
The stress state of any point in the water retaining wall and soil retaining wall were studied based on the elasticity theory and soil mechanics. The method of semi-inverse was used to deduce the stress intensity of the retaining wall in polar coordinate. And if the failure criteria and strength conditions of the retaining wall were known, the working and safety state of the structure could be checked from the stress intensity.
Stability analysis of the infinite slope: The limit equilibrium method is used for the analysis of finite slopes.Slopes extending to infinity do not exists in nature. For all practical purposes any slope of great extent with soil conditions essentially same for all identical depth below the surface are known as infinite slopes.
ANALYSIS AND DESIGN OF A RETAINING WALL. The mass behind the wall from assuming natural slope. Stability of this wall mainly Simplified methods are

This method results lower safety factor than Bishop’s method F s =1.367. The center of the surface with minimum safety factor is the same in both cases. The piling wall To analize the safety factor of the slope we have introduced the same distributed loads on the top of the slope (80 kN/m 2). We have also introduced the same soil characteristics.

calculator or a spreadsheet program, or using slope stability charts. An approximate check of calculations can also be performed using the Ordinary Method of Slices, although the OMS will usually give a lower value for the factor of safety, especially if φ is greater thanzero and pore pressures are high.

To address these challenges, we provide the technical basis and economic solution for severe slope challenges, problematic soil conditions and land development needs. Strata Systems uses primary and secondary Stratagrids, combined with traditional erosion protection products and vegetation to provide sound engineered solutions for reinforced steep slopes.
to use for a wide range of slope stability Retaining Walls; Soil Movement & Stability; slope stability analysis using the slices methods and presents the
retaining wall as it rotates about the toe of the structure. The overturning force is the sum of each destabilizing force times its moment arm. The stabilizing force, or righting moment, is the product of the weight of the retaining wall and its moment arm, which is the horizontal distance from the toe to the center of gravity of the wall.
