An optional cast-in-place concrete waler is shown at each anchor row location. The concrete walers are cast against the earth after installation of the helical anchors and prior to excavation for the next lift. Concrete walers can reduce the required thickness of shotcrete for the remaining facing. The walers also improve punching resistance at the helical tie back locations.

In this paper, a localization method for multistatic SAR based on convex optimization without DCE is investigated and the influence of BRS estimation error on localization accuracy is analysed.
