- ReSSA 大地工程軟體
介紹ReSSA (3.0) is an interactive program used to assess the rotational and translational stability of slopes. It was specially developed to allow for convenient inclusion of horizontally placed reinforcement, thus enabling the design and analysis of mechanically stabilized earth slopes. Reinforcement properties follow AASHTO guidelines. However, the user can override all default values.
ADAMA Engineering had developed the copyrighted program ReSSA Version 1.0 for the US Federal Highway Administration (FHWA). [Link to FHWA website announcing the release of version 1.0] Version 1.0 has been designated exclusively for use by US State Highway Agencies and by US Federal agencies. ADAMA Engineering offers version 3.0 to the public. This version includes an important enhancement allowing exploration of 3-part wedge mechanism, with and without reinforcement, using Spencer's method. ReSSA (3.0) can be used as a generic slope stability program considering circular slip surfaces (Bishop Method) and 2- or 3-part wedge slip surfaces (Spencer method). An instructive article demonstrating the use of ReSSA (3.0) in a case of complex geometry of reinforced tiered slope can be downloaded. Download Article. ReSSA (3.0) can also be used for base-reinforced embankment over soft soil.
MSEW(3.0) is an interactive program for the design and analysis of mechanically stabilized earth walls. It follows the design guidelines of AASHTO98/Demo 82, AASHTO02/FHWA-NHI-00-043, AASHTO07, or NCMA97/98. Note that AASHTO98/02 is based on allowable stress design (ASD) whereas AASHTO07 is based on load resistance factor design (LRFD).
2D Suite is a PLAXIS Software package which includes PLAXIS 2D V9, Dynamics, and PlaxFlow. It makes up a finite element package intended for the two dimensional analysis of deformation and stability in geotechnical engineering. It is a robust and user-friendly finite element package, developed for Geotechnical Engineering. The 3D Suite package contains the programs 3DTunnel and 3DFoundation. These programs combine to form a 3D geotechnical finite element package especially designed for the three-dimensional analysis of deformation and stability in tunnel & foundation projects.
STEDwin only - If you do not plan to purchase GSTABL7 v.2, then STEDwin 2.7 is also available separately for working with your current Purdue or PennDOT STABL programs. STEDwin is the smart editor for PCSTABL which runs under Win95, 98, NT, 2000, and XP. It allows on-screen data entry and modification similar to a spreadsheet. STEDwin itself performs no stability analysis but allows the user to concentrate on the engineering aspects of slope stability analysis while it takes care of writing the data files in the format expected by the slope stability analysis program.
