Learn about sloped and vertical open excavation cuts.
Learn about the principal factors influencing trench stability.
Learn the primary considerations for slope design in different soil types.
Learn about the two basic types of excavations: “open excavations” where stability is achieved by providing stable side slopes, and “braced excavations” where vertical or sloped sides are maintained with protective structural systems that can be restrained laterally by internal or external structural elements.
