Urbanization and Rural Development in the Beijing–Tianjin–Hebei Metropolitan Region: Coupling-Degree Model
Publisher: American Society of Civil Engineers
Abstract: Regarding urbanization as an interactive process between urban and rural development, this paper attempts to reveal the correlation between urbanization and rural development in China through comprehensive quantitative ...
Analysis on the Influence of Geometric Parameters of a Circular Steel Pipe with Flange Plates on Surface Settlement
Publisher: ASCE
Abstract: Surface settlement is considered a key indicator in the pipe jacking procedure of the steel tube slab (STS) pipe-roofing method. Commonly, the existing equations for this safety indicator are applied in the process of ...
Enhancing Coagulation Prediction in Water Treatment Using a Similarity Score–Based Piecewise Machine Learning Model
Publisher: American Society of Civil Engineers
Abstract: Coagulation is vital in water treatment, but predicting coagulant doses using mechanistic models is challenging due to complex processes. Traditionally, jar testing is used, but it struggles with varying water quality. ...
Reliable Fatigue-Life Assessment of Short Steel Hanger in a Rigid Tied Arch Bridge Integrating Multiple Factors
Publisher: American Society of Civil Engineers
Abstract: With higher requirements in stiffness and strength, the running safety of high-speed railway bridges is more sensitive to structural damage. Compared with long steel hangers, short steel hangers sustain greater damage under ...
Slurry Support Mechanism for Shield Tunneling Considering Slurry Infiltration and Cutter-Disk Cutting Effect
Publisher: American Society of Civil Engineers
Abstract: This study aims to clarify the mechanism of slurry support and its effect at different stages of slurry infiltration in shield construction. The analysis of various expressions of slurry support throughout the entire ...
Risk Analysis of the Opening of Shield-Tunnel Circumferential Joints Induced by Adjacent Deep Excavation
Publisher: American Society of Civil Engineers
Abstract: Deep excavation projects in urban areas may adversely affect underlying tunnels. Differential settlement and additional stresses in existing tunnels occur frequently due to excavation construction, which leads to the opening ...
Modified Duncan-Chang Constitutive Model for Modeling Supported Excavations in Granular Soils
Publisher: ASCE
Abstract: Numerical analyses have been widely used to investigate the stability of deep excavations. The results of this type of analyses rely on the constitutive model that is adopted for the analyses. Although many advanced ...
