RISControl of Molybdenum Emission by Sorbents: Equilibrium Analysis
Publisher: American Society of Civil Engineers
Abstract: Emissions from fossil fuel combustion containing various heavy metals such as molybdenum are of public concern due to their adverse effects on human health and the environment. In this study, thermodynamic analyses were ...
Performance and Three-Dimensional Analyses of a Wide Excavation in Soft Soil with Strut-Free Retaining System
Publisher: American Society of Civil Engineers
Abstract: This paper presents the results of monitoring the diaphragm wall and ground surface settlement and three-dimensional finite element analyses of the Xizhi excavation case history. The Xizhi excavation was 9.2 m deep, covering ...
Loop Current Growth and Eddy Shedding Using Models and Observations: Numerical Process Experiments and Satellite Altimetry Data
Publisher: American Meteorological Society
Abstract: ecent studies on Loop Current?s variability in the Gulf of Mexico suggest that the system may behave with some regularity forced by the biannually varying trade winds. The process is analyzed here using a reduced-gravity ...
Effect of Mesoscale Eddies on the Taiwan Strait Current
Publisher: American Meteorological Society
Abstract: his study shows that mesoscale eddies can alter the Taiwan Strait Current. The 20-yr data-assimilated Japan Coastal Ocean Predictability Experiment 2 (JCOPE2) reanalysis data are analyzed, and the results are confirmed ...
Three‐Dimensional Dynamic Analysis of Dam‐Water‐Sediment Systems
Publisher: American Society of Civil Engineers
Abstract: Using the finite element method, a consistent transmitting boundary is developed for the treatment of the infinite water‐sediment region in the three‐dimensional analysis of dams. The boundary can be coupled directly with ...
A Study of the Failure Mechanism of Braced Excavations Using 3D Finite-Element Analysis
Publisher: ASCE
Abstract: This study aims to investigate the failure mechanism of structural support systems in braced excavations. The three-dimensional finite-element method (FEM) was used to model the complexity of real geometry by considering ...
Numerical Study of the Effect of Ground Improvement on Basal Heave Stability for Deep Excavations in Normally Consolidated Clays
Publisher: American Society of Civil Engineers
Abstract: The ground-improvement technique is commonly used to restrain the wall displacement induced by excavation and resist the basal heave for deep excavations in soft clays. In this paper, a three-dimensional finite-element ...
Performance of Excavations with Cross Walls
Publisher: American Society of Civil Engineers
Abstract: This paper presents the performance of an excavation with cross walls based on field observations and numerical analysis results. A small strain constitutive model was used in the analysis. By comparing the movements of ...
Development of a Suitable Operation Procedure for Electroosmotic Chemical Soil Improvement
Publisher: American Society of Civil Engineers
Abstract: To expand the improvement region, a series of electroosmotic chemical tests was performed to study the mechanism of improvement. Results showed that injection of calcium chloride and sodium silicate solutions could improve ...
Evaluation of Factors of Safety against Basal Heave for Deep Excavations in Soft Clay Using the Finite-Element Method
Publisher: American Society of Civil Engineers
Abstract: This study investigates basal heave stability of deep excavations in soft clay using FEM with reduced shear strength. Three failure and one excessive deformation case histories are utilized. Three methods of estimating ...
