TP – 1123 An Introduction to Structural Stability of Flood Walls for Professional Engineers

Description

This discussion presents information for stability analysis of retaining walls and inland and coastal flood walls. The methods of analysis to determine overturning and sliding stability and to assess bearing capacity are discussed. The forces as determined are used to assess overturning stability and bearing capacity. In certain cases as described in this discussion, the same forces computed for overturning may be used to check sliding stability. In other cases, sliding stability should be computed by the multiple wedge iterative method or by an adjustment of the driving and resisting wedge forces based on the factor of safety required, both of which are discussed in this discussion. Loading conditions for the various types of walls and the acceptable criteria for each loading condition are given for each of the stability analyses.
