Three-Dimensional Analysis And Inclinometer Measurements In Deep Circular Excavation In Sand Soil, Hermil Rizki Hanifah, Paulus Pramono Rahardjo, Aswin Lim

Rock and Soil Mechanics

This paper presents the results of the inclinometer monitoring and back analysis using three-dimensional finite elements in the scale pit deep excavations. Scale pit is a deep circular excavation construction with a depth of −27 m and a total diameter of 26 m. The soil layer above from the final excavation is dominated by a sandy soil layer. The retaining wall construction is a secant pile reinforced with waler beams at each excavation stage. The hardening soil model was used as soil constitutive model. The results of the back analysis show that the trend of wall deflection is close to …
