Retaining Wall Tool (Metallic-strip)
Geometry of retaining wall with metallic-strip reinforcement
Tips
This tool is for analysis of retaining walls with metallic strip reinforcement, as shown in the figure above.
Two homogenous soil layers are considered in the analysis.
The Rankine earth pressure theory is used.
No surcharge is considered in this tool.
For the backfill, the cohesion c
1
is assumed to be zero.
The height of retaining wall H is suggested to be an integral multiple of S
V
vertical spacing of ties.
The Extra thickness of tie due to corrosion during life span t
cor
can be calculated by corrosion rate times life span of the structure.
All the input parameters should be positive.
For "nan", "0" or "inf" displayed in Results, please check your input parameters.
