Abstract

The relative contributions of temperature, earth pressurs and construction loading on the resulting stresses in excavation support members were evaluated by analyses of the results of strain gauge measurements obtained at a 10 m deep excavation through clay. Temperature impacted both axial and bending stresses in the supports. It is shown that axial thermal loading may constitute 50% of the axial strut load. Bending stresses developed as a result of thermal variations through the cross-section of a support member, self-weight of the supports, and unexpected construction loadings. The bending introduced large stresses as well. The proximity of a support member to a corner of the excavation had little effect on the stress in the member.
