We would like to be able to model piles in Slope, with specified mobilised shear resistance across the failure surface. This would ideally (in future) be linked to a mobilised shear-displacement profile for each pile derived from Alp. The mobilised shear can be specified apriori for the pile or pile group, or determined from Newmark Sliding Block analysis with the shear-displacement curve. Get in touch for details.

When constructing a pile with temporary casing, the pile diameter through the cohesionless (cased) soils is much greater, resulting in an increased shaft area and thus capacity.

Currently Pile can only specify one (the minimum) pile diameter.

It would be very useful to enable a check that the characteristic pile shaft resistance is greater than the characteristic pile action.

i.e. a factor of >1 on the shaft capacity alone

Pile currently treats soils in two broad catergories: drained and undrained, the drained soils have only an angle of friction and the undrained only the undrained cohesion. It would be nice if c-phi soils (e.g sandy clays, clayey sands) can also be considered.

Pdisp is often used to derive subgrade reaction stiffnesses for input into GSA by manually dividing the applied pressure by the settlement results to calculate the equivalent subgrade reaction springs. The conversion could be built into PDsip itself and a subgrade reaction contour could be plotted. There’s a possible automation linkage with GSA.

See also "Direct output of equivalent subgrade reaction stiffnesses". Pdisp allows the input of horizontal loading on a vertical plane. Equivalent subgrade reaction stiffnesses (reaction springs) for wall elements could be obtained from applied horizontal pressure and resulting movements.

At present , we need to change coordinates of strata to change slope section inclination angle , it will be great if we can change slope angle on screen directly. This will be useful for mining engineering problems where height of the bench remains constaant but user want to change slope angle.
