Seasonal joint deformations within an immersed tunnel are important indicators to assess structural behavior and therefore should be monitored in detail. In this study, distributed optical fiber sensors (DOFS) applied precisely measure the seasonal for first time. Measurements over a one-year period specifically reveal impact of temperature variations on opening uneven settlement deformation. Field monitoring shows that variation exhibits cyclic is strongly correlated with change. The...
The development of modern cities has often led to increased traffic congestion and limited usable space. One effective solution these problems is construct roadway tunnels, which can expand urban space alleviate congestion. However, building large underpass tunnels in areas, especially soft ground, presents technical challenges owing its extensive environmental disturbance. pipe-umbrella box jacking method offers a promising as this does not require breaking the ground from surface or...
Monitoring the deformations of immersed tunnels is important during entire tunnel service life to assess structural integrity tunnel. Conventional joint deformation monitoring based on manual levelling measurements and normally occurs only at multi-year intervals, which does not allow capture short term behavior. In this study a new system using distributed optical fiber sensors (DOFS) developed. A special sensor layout designed that allows simultaneous both horizontal opening vertical...
Pipe jacking has been the dominant trenchless technology for constructing small (<2 m) to medium-diameter (<4 tunnels. Uncertainties and construction difficulties increase significantly when diameter of tunnel exceeds 4 m. This paper presents a case study largest concrete pipe-jacking project in world, sewerage along Jinshan Lake, Zhenjiang, China. In this project, an underwater with 4.67 m was constructed by earth pressure balance (EPB) method. The reports background, geological...
The short-term deformation behavior of immersed tunnels due to daily or monthly temperature changes and tidal variations is often not monitored but forms important input for a structural health assessment the tunnel. In this study, distributed optical fiber sensors (DOFSs) are used monitor (daily monthly) an Joint opening relative settlement differences between tunnel elements simultaneously at subhour intervals. Measurements show that variation in joint strongly correlated with change, gap...
Industry 4.0 was proposed by Germany, which will bring a revolution in manufacturing. How does China's manufacturing sector deal with this revolution? The key is to identify problems and provide solutions. Based on the analysis of statistical data qualitative analysis, paper carries out an in-depth current situation Then, main industry were analyzed. Finally, puts forward concrete countermeasures for sector. as follows: pushing technological innovation strengthening cooperation...
Distributed optical fiber sensors (DOFS) allow for distributed strain sensing and can be installed to function as extensometers measuring point-displacements. This paper discusses the metrics of optimal selection point-displacement measuring. Key include physical structure, mechanical parameters light transmission coefficients. Calibration tests verification properties are designed results four types presented. Finally, creep relaxation behavior fibers is discussed based on manual tension...
Structural health monitoring is essential for the lifecycle maintenance of tunnel infrastructure. Distributed fiber‐optic sensor (DFOS) technology, which capable distributed strain measurement and long‐range sensing, an ideal nondestructive testing (NDT) approach linear infrastructures. This research aims to develop a sensing network utilizing DFOS structural integrity assessment concrete immersed tunnels. The primary innovations this study lie in development general flowchart establishing...
MYB transcription factors play crucial roles in various stages of plant growth and development. Bioinformatics analysis revealed that wheat TaMYB4-1A contains two conserved domain. The coding region is 792 bp, encoding 263 amino acids. a hydrophilic protein, its encoded protein localized the cell nucleus. Evolutionary tree indicates TaMYB4 shares closest relationship with Aegilops, barley, rye. Tissue-specific expression expressed roots, stems, leaves, seeds 14 days post-flowering, highest...
This study analyzes the impact of air pollution on city in which customers are located trade credit strategy their suppliers. Following framework environmental stress theory, we hypothesize that suppliers change to grant less cities with severe pollution. Our findings consistent our hypothesis. We find adverse effects occur through financial constraints, operating risk, and customers' default corroborating underlying logic proposed Additional analyses suggest changes a supplier's more...
