Stability of Three-Dimensional Slurry Trenches with Inclined Ground Surface: A Theoretical Study

Stability of Three-Dimensional Slurry Trenches with Inclined Ground Surface: A Theoretical Study

Stability of slurry trenches is an important issue during the construction of the groundwater cutoff walls and diaphragm walls, and thus gradually draws attention. In this paper, a theoretical method for a three-dimensional trench model with an inclined ground was proposed. Based on the Coulomb-type...
