SoilStructure Software, Inc. (TM) makes Substructural Engineering Software & answers its phones. We solve your questions on the spot. We only get about 4 technical questions a month for ALL OUR products.After more than a quarter century of consulting engineering work, I have come to the conclusion that our project engineers need robust software with familiar inputs. They don't need complicated & obscure parameters.  We have familiar inputs and capable programs that get the job done.

SoilStructure Software lets you, the customer, decide whether to LEASE or PURCHASE. We give you both options.  We also don't charge any ongoing "Maintenance Fees".  It is our responsibility to have up to date software available for sale to our clients.  So you will never pay us any "Annual Fees".

USB dongle option available

How to Design a Cantilever Soldier Pile (Embedded Retaining Wall)

Design Introduction When excavation heights exceed 5 ft (1.5 m), we need to design a lateral support system. This is often a cantilever soldier pile or embedded retaining wall. A cantilever wall of this kind is permissible up to about 17 ft (5.2 m). Backfill Earth Pressure We can determine the backfill earth pressure using […]

Ascending Backfill & Equivalent Fluid Pressure in Retaining Walls

Definition: Equivalent fluid pressure is a simplification of backfill earth pressure against retaining structures. If the backfill behind a cantilever retaining wall or restrained (basement) wall is level, we can use the equivalent pressure. For a cantilever retaining wall, level & drained condition (subdrain), the equivalent fluid pressure is simply the product of Ka * […]
