  3. Include pile pinning in Slope

    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.

  4. Limit on tension in props

    Please can you allow a limit to be set to prevent props going into tension? Currently a multi-propped wall with no embedment doesn't fail as the top prop goes into tension.

  5. Minimum equivalent fluid pressure

    A new update allows you to edit the MEFP at each stage and in each material. However, it defaults to y0=0 at each stage and therefore is not applied unless you go through each stage and change this. Please can the MEFP default to the top node level unless specified otherwise?

  6. Extend Pile to model embedded retaining walls as a rectangular panel

    Where embedded pile retaining walls carry axial loads, it is common practice to analyse the section as a rectangular panel rather than individual circular piles (with a reduced end bearing co-efficient akin to a deep strip footing).

    To date, we have achieved this by modelling an under-ream pile with different shaft and base diameters. However, it would be simpler and clearer if Pile could analyse a rectangular section. This would also be beneficial for calculation of axial resistance for diaphragm wall panels.

    Refer to method of Hov et al from 2010 DFI Conference (attached).

  7. Multiprocessing and result plotting improvements

    Add parallel processing capability to SIREN so that two, four or eight time histories can be run in parallel (depending on processor capabilities) rather than sequentially. (NB: This capability is currently a feature of Deepsoil).

    Consider adding more than one soil profile for analysis to an input file, as we typically run three versions of a soil profile to consider uncertainty in the input stiffness profile (upper, lower bounds and best estimate). The same time histories are run through each profile.

    With typically three stiffness profiles considered per soil profile, and 7-pairs of records (14 No.) per profile, and often…

  8. Specify soil nail bond strength for each strata

    The ability to specify a single bond strength between a soil nail and the surrounding soil (using CIRIA guidance or preliminary test data) does not work if the soil is layered. The user should be able to specify the bond strength for each strata.

  10. Graphical output shall show all wall dimensions on screen

    Hi , currently graphical output is not showing wall dimensions, its good if it shows all dimensions and can be exportable to auto cad program

  11. Add inclined Piles

    Alp now handles only perfectly vertical piles, it could be nice if it handles inclined piles

  14. Enable SLS check as part of Eurocode (ULS) calculations

    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

  15. Add ability to select / specify casing diameter in PILE

    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.

  16. Changing slope angle interactively on graphical input

    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.
