Spreadsheets cannot easily calculate global (deep-seated) slope stability failure mechanisms. For circular or non-circular slip surface analyses, you must export soil profiles to specialized software like Slide2, GeoStudio Slope/W, or Re穩定.
: Cells are highlighted in yellow for soil friction angles, unit weights, and surcharge loads (like traffic or nearby buildings).

Mechanically Stabilized Earth (MSE) walls are the backbone of modern civil infrastructure. They support highway overpasses, hold back massive embankments, and maximize usable land on commercial jobsites. However, designing an MSE wall requires rigorous calculations that balance internal stability, external stability, and global safety factors.
Dropdown menus for selecting:
A well-structured MSE wall design spreadsheet is an invaluable tool for preliminary design, peer review, and education. It enables engineers to understand the sensitivity of safety factors to input parameters. However, due to the risk of hidden errors and missing failure modes (global stability, settlement, or connection failure), spreadsheets should be used as part of a robust quality assurance process—never as the sole basis for final design of permanent, life-safety-critical MSE walls.
