In an anchored shoring application where you know the layering status of the soil profile, the vertical spacing of the anchors placed along the excavation depth (H) can be determined primarily according to which of the following options? a. All anchors should be positioned close to the surface as the excavation top level will be more displaced. b. It should be determined according to the slip plane. c. The top row anchor should be determined at a depth to balance the cover load, and in the vertical shoring element between two consecutive lower and upper anchors, the cantilever should be determined to prevent operation. d. It should be determined according to the magnitude of the pretensioning force. e.It is determined by the groundwa
