TP – 1122 An Introduction to Excavation for Structures for Professional Engineers

Description

This discussion covers the methods of evaluating the stability of shallow and deep excavations. There are two basic types of excavations:
“open excavations” where stability is achieved by providing stable side slopes
“braced excavations” where vertical or sloped sides are maintained with protective structural systems that can be restrained laterally by internal or external structural elements. In selecting and designing the excavation system, the primary controlling factors will include: soil type and soil strength parameters, groundwater conditions, slope protection, side and bottom stability,vertical and lateral movements of adjacent areas, and effects on existing structures.
