Influence of Confining Pressure on Nonlinear Failure Characteristics of Coal Subjected to Triaxial Compression
The stress of a coal seam increases with an increase in the mining depth, which makes the failure mechanism of a coal mass more complex. To reveal the deformation and failure law of deep coal, a series of triaxial experiments was carried out via laboratory experiments and numerical simulation experiments to analyze the influence of the confining stress on the nonlinear failure characteristics of coal. Based on the crack-propagation model, the val…

The association between perceived residential environment, social interaction and subjective well‐being of China's elderly migrants
With the rapid growth in both urbanization and the ageing of the population, elderly migrants have become a more prominent group in urban China. Previous studies have shown that elderly migrants are a vulnerable group in terms of subjective well‐being (SWB) and studies have emphasized the role of their socioeconomic status (SES) and family‐related attributes (FRA) on their SWB. However, there is less attention on whether the perceived residential…
Assessing personal travel exposure to on-road PM2.5 using cellphone positioning data and mobile sensors
PM 2.5 pollution imposes substantial health risks on urban residents. Previous studies mainly focused on assessing peoples' exposures at static locations, such as homes or workplaces. There has been a scarcity of research that quantifies the dynamic PM 2.5 exposures of people when they travel in cities. To address this gap, we use cellphone positioning data and PM 2.5 concentration data collected from smart sensors along roads in Guangzhou, China…
Multistage Impacts of the Heavy Rain Process on the Travel Speeds of Urban Roads
Heavy rain causes the highest drop in travel speeds compared with light and moderate rain because it can easily induce flooding on road surfaces, which can continue to hinder urban transportation even after the rainfall is over. However, very few studies have specialized in researching the multistage impacts of the heavy rain process on urban roads, and the cumulative effects of heavy rain in road networks are often overlooked. In this study, the…
