RISActive Earth Pressure against Rigid Retaining Walls Subjected to Confined Cohesionless Soil
Publisher: American Society of Civil Engineers
Long-Term Longitudinal Deformation Characteristics of Metro Lines in Soft Soil Area
Publisher: American Society of Civil Engineers
Abstract: Metro lines buried in soft soil in coastal regions will inevitably suffer long-term uneven deformation during operation. In this study, the long-term deformation characteristics of metro lines in Shanghai soft deposits are ...
Effect of Dewatering in a Confined Aquifer on Ground Settlement in Deep Excavations
Publisher: American Society of Civil Engineers
Abstract: Dewatering must be conducted for shallow confined aquifers located below deep excavations. However, its effects on ground settlement remain unclear, due to the complicated seepage and stress condition of the strata. In ...
One-Dimensional Reverse Consolidation Model for Basal Soil from Deep Excavation Based on the Continuous Drainage Boundary
Publisher: ASCE
Abstract: Excavation-induced unloading effects and dewatering-induced groundwater seepage inevitably result in basal soil reverse consolidation in deep excavation. However, this reverse consolidation process is rarely considered ...
Nonlinear Permeability Characteristics of Shanghai Clay and Their Influence on Embankment Deformation
Publisher: American Society of Civil Engineers
Abstract: Abstract The relationship between permeability and deformation of Shanghai clay has rarely
been reported, and the influence of the variation of hydraulic conductivity with deformation
on embankment deformation is not clear. ...
Semianalytical Solution for Earth Pressure of Narrow Granular Backfill with a Log-Spiral Failure Surface behind Retaining Walls under Translational Mode
Publisher: ASCE
Abstract: A novel semianalytical method is proposed to estimate the earth pressure exerted on rigid retaining walls supporting a narrow granular backfill in this study, which is based on the assumption of a log-spiral failure surface. ...
Numerical Investigation of the Effect of Stratum Hydraulic Conductivity on Performance of Deep Excavations in an Aquifer–Aquitard System
Publisher: ASCE
Abstract: Engineering practices indicate that stratum hydraulic conductivity (SHC) has a significant influence on deep excavations. However, this influence has been ignored in previous studies with undrained analyses. In this study, ...
Predicting Wall Deflections for Deep Excavations with Servo Struts in Soft Clay
Publisher: ASCE
Abstract: Axial forces can be artificially adjusted in deep excavations braced with servo struts to reduce excavation-induced deformations. The interactions among the servo strut, retaining wall, and retained soil must be considered ...
Effects of Overconsolidation and Structural Behaviors of Shanghai Clay on Deformation Caused by Deep Excavation
Publisher: American Society of Civil Engineers
Abstract: Shanghai clay exhibits overconsolidation, soil structural, and small-strain characteristics. While there have been several studies on the effects of small-strain characteristics on the deformation caused by deep excavation, ...
Experimental Investigation of Passive Failure against Retaining Structures under Various Displacement Modes
Publisher: American Society of Civil Engineers
Abstract: This study conducted model tests to simulate the passive failure of granular soils under different displacement modes, including the translational and rotation modes concerning different pivot points, to investigate the ...
