Analytical Problems in Modeling Slurry Wall Construction.

摘要

Three aspects of slurry wall construction are considered. These are the alteration of the initial stress state in the soil adjacent to the wall by the trench excavation and support process,the further alteration of the initial stress condition for a cast-in-place wall by placement of the high density concrete slurry and subsequent shrinkage of the slurry upon set-up,and the modification of the soil structure interface due to the impregnation of slurry upon set-up,and the modification of the soil adjacent to the wall and the formation of a slurry cake between the soil and the wall. Analytical methods,including finite element analysis and associated fields,for modeling slurry wall construction are reviewed and evaluated.
