Abstract: Soldier pile retaining wall is composed of reinforced concrete soldier pile and the lagging plates in between, which can transfer lateral force to the solder pile and stabilize the soil slope through the soldier pile and laggings. The soldier pile and lagging wall can also be applied in constructing retaining walls in fill condition. The cast-in-place reinforced concrete soldier pile can be constructed first before the fill operation; then the lagging can be installed along with the fill to the desired final height. This method can be used in projects that require fill and retaining wall where the retaining structure can be constructed in advance. Based on the project practice, this paper presents the advanced construction of the soldier pile and lagging retaining wall in details. Ans provides a refence for the future construction of the similar projects.

Key words: Soldier Pile and Lagging Retaining Wall, Lagging in Retaining Wall, Advanced Construction
