Cantilever Sheet Piling

[RacerChuck]

Does anybody know of any Freeware/Shareware programs that will do Coulomb/Rankine Calcs for Earth Pressure, and solve for Sheeting Size and Penetration?

Any and all help is appreciated.....

I thought that there were a couple of Army Corps programs, SHTWALL and CANTWALL that did earth pressures by various methods

Mr. Redman,

As the previous correspondent indicated, the Corps of Engineers does offer a program for computing earth pressures for cantilevered and anchored walls. The program is named CWALSHT and was produced by the ITL/GL at Waterways Experiment Station. The program performs many calculations quite proficiently, but it is not terribly robust. A few notes:

(1) Carefully check the pressure diagrams generated by the programs. A version of this program circa 1996 produced unusual spikes in the diagram due to an interpolation algorithm used at strata breaks.

(2) The anchored wall methods do not compute apparent pressure envelopes (e.g., Terzaghi and Peck) and do not permit multiple braces.

(3) The "sweep" option is intended to maximize wall forces by investigating a number of assumed rupture surfaces at each depth along the wall. This option does not operate properly.

(4) For sloping backfill, you are not permitted to have a strata break coinciding with the top of the wall.
