In 2012, a client reached me to get to a shoring solution for an excavation.
'Shoring' is a civil engineering technique to retain the earth in deep excavation.
The Client requested a cost effective solution to support 7 m of earth in a deep excavation. I provided two options with cost comparison.
1. Driving of steel sheet pile
2. Soldier piles.
Option -2 was economical and technically feasible. owing to existence of deep sandy layer in the sub soil profile , the driving of sheet piles predicted to be difficult.
Chosen the sheet pile option, I developed an Excel
spread sheet to calculate the driving depth of the steel H iron . Simultaneously I developed a finite element model for the same using Stadd Pro.
I was compelled develop my own techniques to determine the driving depth of H iron as literature on the FE modeling using general FE software was limited.
I did several modelling but did not
get the exact bending moment shape as it should be. After several attempts of different methods, I was succeeded in getting correct shape of
the bending moment diagram and was in a position to decided the driving depth of the pile. I
compared this results with the excel spread sheet calculation and the results were matched.
