Image-Assisted Total Station Camera Mounting Error Correction Model and Analysis
Publisher: ASCE
Abstract: Image-assisted total stations (IATSs) have extensive application prospects in astronomic surveys, deformation monitoring, precision engineering surveying, and topographic mapping. During image processing of data, the angle ...
Astronomical Azimuth Determination by Lunar Observations
Publisher: American Society of Civil Engineers
Abstract: The moon is the brightest celestial body in the night sky, and it is of some value when determining the astronomical azimuth on a cloudy or foggy night or in a light-polluted city when there is no visible star. Based on ...
Precise Astronomical Orientation Using Multiple Stars at Their Culmination and Analysis of Different Regression Models
Publisher: ASCE
Abstract: Precise determination of the astronomical azimuth using the local hour angle (LHA) of Polaris is only applicable in northern middle latitudes. Therefore, to achieve fast and precise astronomical orientation in any part of ...
Crack Coalescence Morphology in Asphalt Mixtures under Compressive Loading
Publisher: ASCE
Abstract: Cracking coalescence is the linking process of multiple cracks; the ordinary differential and partial differential equations cannot be solved at the crack coalescence positions. To solve these shortcomings, the asphalt ...
Development of a DEM-Based Method for Modeling the Water-Induced Failure Process of Rock from Laboratory- to Engineering-Scale
Publisher: ASCE
Abstract: The time-dependent hydromechanical behavior of rocks is crucial to assessing the long-term stability of rock engineering, such as reservoir rock slopes and underground waste storage facilities. This research aims at ...
Experimental Investigation on Spray Evaporation and Dispersion Characteristics of Impinged Biodiesel-Butanol Blends
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The objective of the investigation is to explore the spray evaporation and dispersion characteristics of impinged biodiesel-butanol blends at various n-butanol ratios (0, 10%, 30%, 50%) and ambient conditions. A total of ...
Physical Model Tests and Discrete-Element Simulation of Pile and Soil Displacement Response Induced by DOT Shield Tunneling Based on Transparent Soil Technology
Publisher: ASCE
Abstract: With the advantages of saving underground space, small construction impact, and saving cost, the double-O-tube (DOT) shield tunneling construction technology has been used many times in the tunnel construction of particular ...
