- 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.
TALREN 4 is ideal for checking the stability of geotechnical structures, with or without reinforcements: natural slopes, cut or fill slopes, earth dams or dikes. It takes into account various types of reinforcements such as: anchors and soil nails, piles and micropiles, geotextiles and geogrids, steel and polymer strips.
GeoCoPS is an interactive program for the design of geosynthetic tubes. For a given problem, the geometry of the tube and the circumferential and longitudinal required strength of the encapsulating geosynthetic are produced. The computations account for reduction factors related to seam strength, durability, creep and installation damage. Results are obtained by solving a differential equation subjected to design constraints.
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.
