GeoStru - SPW Sheet Pile Walls Design
Sheet walls are relatively thin, vertical structures, embedded in terrain to a depth sufficient to support an uphill embankment/downhill excavation thrust, including water and surcharges. This type of structure can be constructed of driven prefabricated steel pile sections, adjacent, bored cylindrical piles, and reinforced concrete sheet elements usually produced on site. The methods used for analysis / verification are: Limit Equilibrium Method (LEM) and Finite Elements Method (FEM). The methods mentioned are of increasing complexity from both the numerical point of view and for the amount of geotechnical parameters necessary for the calculation.
Sheet pile wall design – SPW : Software for the desing and analysis of sheet pile walls, drilled piles and diaphragm walls.
