Predictions of Deep Excavation Responses Considering Model Uncertainty: Integrating BiLSTM Neural Networks with Bayesian Updating
Publisher: ASCE
Abstract: Predictions of excavation responses frequently differ from monitoring data due to geotechnical uncertainties. This paper proposes an efficient Bayesian updating approach for excavation responses that considers the uncertainties ...
A New Approach for Dewatering Slurry: Vacuum Preloaded Geotextile Tube
Publisher: American Society of Civil Engineers
Abstract: The geotechnical tube technology has been widely used in the dewatering treatment of high-water-content slurries, such as engineering waste muds, mine water sludges, and dredging slurries. However, the existing engineering ...
Percolation Behavior of Soft Clay under Vacuum Suction
Publisher: American Society of Civil Engineers
Abstract: The clogging induced by particle transport is often mentioned in the practice of vacuum preloading, but the percolation behavior of soft clay under negative pressure is still not clear. To understand this, the percolation ...
Large-Strain Self-Weight Consolidation of Dredged Sludge
Publisher: ASCE
Abstract: Prediction for self-weight consolidation of dredged sludge is important for its reuse in civil engineering applications. In this work, considering the special nonlinear relationships of e – k and e – σ′ for dredged sludge, ...
Cyclic Behavior of Saturated Clays in Plane Strain State
Publisher: ASCE
Abstract: The cyclic behaviors of soils in the plane strain state have rarely been studied in laboratory tests, while the plane strain hypothesis may have applications on the traffic-induced cyclic properties of subgrade soils beneath ...
Consolidation Considering Clogging Effect under Uneven Strain Assumption
Publisher: ASCE
Abstract: In land reclamation projects, the vacuum preloading method has been widely used to strengthen dredged fills by removing water. However, during the improvement process, clogging inevitably occurs in the drains and soils, ...
