RISAutomatic Detection of Rail Surface Cracks with a Superpixel-Based Data-Driven Framework
Publisher: American Society of Civil Engineers
Abstract: A bilevel superpixel-based framework for the vision inspection of rail conditions and automatically detecting rail surface cracks is proposed in this paper. The simple linear iterative clustering (SLIC) algorithm is applied ...
Stability of Unsaturated Soil Slopes with Cracks under Steady-Infiltration Conditions
Publisher: American Society of Civil Engineers
Abstract: Most classical approaches for evaluating the stability of soil slopes with tension cracks are performed under dry and/or saturated conditions. The suction-induced effect of unsaturated soils is generally neglected in ...
Stability of Unsaturated Soil Slopes with Cracks under Steady-Infiltration Conditions
Publisher: American Society of Civil Engineers
Abstract: Most classical approaches for evaluating the stability of soil slopes with tension cracks are performed under dry and/or saturated conditions. The suction-induced effect of unsaturated soils is generally neglected in ...
Temporal and Spatial Distribution of Maximum Daily Precipitation in Hengduan Mountainous Region of China and Its Probability Characteristics
Publisher: ASCE
Abstract: People often need precipitation data when building hydraulic engineering, especially the maximum daily precipitation data, so it is very important to study the maximum daily precipitation for hydraulic engineering. The ...
Analysis of Shear Characteristics of Recycled Concrete Aggregate–Geogrid Interface
Publisher: American Society of Civil Engineers
Abstract: Recycled concrete aggregate (RCA) has been widely used as a resource in reinforced soil structures, especially as a substitute for natural aggregate. Direct shear tests were conducted using a dynamic direct shear apparatus ...
Structural Parameter of Structured Soils and Its Application in Constitutive Modeling
Publisher: ASCE
Abstract: Structured soils exhibit significantly different mechanical behaviors than reconstituted soils because of the influence of their structure. A theoretical study of the structured soils is carried out in this paper. A newly ...
Three-Dimensional Stability of Unsaturated Soil Slopes Strengthened through Frame Beam Anchor Plates under Steady Seepage Conditions
Publisher: American Society of Civil Engineers
Abstract: The soil is usually unsaturated in practical engineering, and the slope failure surface generally presents three-dimensional (3D) characteristics. Therefore, the traditional plane problem calculation method does not ...
Three-Dimensional Spherical DDA Method for Modeling Friction Problems
Publisher: American Society of Civil Engineers
Abstract: Three-dimensional (3D) discontinuous deformation analysis (DDA) is very suitable for simulating large-displacement behavior of rock masses. One fundamental issue commonly encountered in 3D DDA is 3D friction problems. In ...
Robust H∞ Control and Stabilization of Uncertain Switched Linear Systems: A Multiple Lyapunov Functions Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper addresses robust H∞ control and stabilization of switched linear systems with norm-bounded time-varying uncertainties. First, based on multiple Lyapunov functions methodology, a sufficient ...
Optimum Calculation Method for Cable Force of Concrete-Filled Steel Tube Arch Bridge in Inclined Cable-Stayed Construction
Publisher: American Society of Civil Engineers
Abstract: Iterative initial value of cable force based on influence matrix and linear programming is determined in order to study the cable force of long-span concrete-filled steel tube (CFST) arch bridge using the cable-hoisting ...
