Abstract: Frequent road collapses caused by water leakages from pipelines pose a severe threat to urban safety and the wellbeing of city residents. Limited research has been conducted on the relationship between pipeline leakage and ...

Abstract: Recently, digital twins (DTs) have become a research hotspot in smart manufacturing, and using DTs to assist defect recognition has also become a development trend. Real-time data collection is one of the advantages of ...

Abstract: The tension and slide of surrounding rock are highly inclined to cause dynamic disasters, thus seriously threatening the safety of mine resource recovery. This study proposes a novel method based on the global–local ...

Abstract: Urban road collapse disasters pose a serious threat to public safety and national economic development. The underground cavities formed by drainage pipe exfiltration are the primary cause of road collapse disasters in ...

Abstract: The leakage of drainage pipes is the primary cause of underground cavity formation, and the cavity diameter-to-depth ratio significantly affects the overall stability of roads. However, studies on the quantitative calculation ...

Abstract: In this study, nano-SiO2 was synthesized using the sol-gel method to modify the properties of fly ash-slag geopolymers (FASGs). FASGs with six contents of sol-type nano-SiO2 (0, 0.1%, 0.2%, 0.3%, 0.4%, and 0.5%) and two ...

Abstract: The spring tripole sea surface temperature (SST) anomalies in North Atlantic are an outstanding regional mode of interannual variability. Based on the observed and reanalyzed datasets during 1979–2019, this study reveals ...
