Abstract: A number of parallel lifting operations may take place simultaneously on a prefabricated construction site, likely resulting in workspace overlapping, which is likely to delay the project and even cause accidents. This ...

Abstract: Dry shrinkage cracking of soil is a common phenomenon in nature. The shrinking and cracking of soil have been linked to several geological disasters. To simulate dry shrinkage cracking in soil, we present a continuous 2D ...

Abstract: Ambivalence brings great uncertainty to workers’ decision making of intentional unsafe behaviors. It is of great theoretical and practical significance to find the factors that have significant regulating effect on workers’ ...

Abstract: The theory of viscoelastic collision mechanics is used to explore the rebound and adhesion mechanisms of single aggregates in shotcrete at the meso-level in this study. Abrasive balls with different radiuses were used, ...

Abstract: During concrete pumping, traditional concrete pumps generate pulses due to the swing of the distribution valve and other factors. The pulse phenomenon in concrete pumping leads to poor application performance and limits ...

Abstract: This paper studied the temporal and spatial variation of groundwater levels that characterized the evolution of the groundwater flow field in Xi’an, China, from 1965 to 213, by using the wavelet analysis method. Then under ...

Abstract: To study the influence of chloride erosion on the mechanical properties of steel slag cement–solidified silt soil and the law of chloride ion migration, indoor tests were carried out on the physical and mechanical properties ...
