Abstract As a clean and renewable energy, hydropower holds an important place in energy development for every country. China has the richest resources with 541 GW technical exportable installed capacity, 17% global share. Hydropower is key point of conservation comprehensive utilization to ensure sustainable strategy China. This paper investigates provides summary current situation development. Over past 100 years, China's developed tremendously. The total capacity 341.19 by end 2017 small...
With the wide application of prestressed anchors in high slopes, underground structures, and bridge projects, corrosion problems anchor structure during long-term service have demanded more attention. Because environmental impact structural characteristics, cable is almost inevitable. To obtain status that served over 10 years chambers a power station, field investigation was performed. The environment aggressivity evaluated, inspected investigation. results show effect groundwater stray...
The selection of corrosion test method in the study prestressed anchors is an important issue. In this paper, was conducted with electrolytic method. characteristics anchor cables were examined. effects sodium chloride solution concentration, current, time, and prestress level on studied. applicability cable discussed subsequently. results show that appears to be uniform corrosion. With anchor, central wire basically not corroded, cross-sectional shape outer changes from a round fan shape....
Prestressed anchorage structures have been widely employed in water conservancy, hydropower, mining, transportation, and other industries as an essential reinforcement means such slope underground cavities. The anchor corrosion during service caused widespread concern about the long-term durability of prestressed anchors. Corrosion tests, which can capture initiation development characteristics various engineering environments, gradually become tool study structures. This summarizes five...
Accurate detection of the lining contours is important for evaluation working condition and service life underground structures. A 1:1 test model was constructed to elucidate accuracy non-contact profile with a ground-coupled antenna. In addition, at various distances qualitatively quantitatively analyzed. At below 80 mm, it found that radar scanning map well-defined could be obtained when gain processing techniques were applied measurement signal. As distance above 160 measured signal must...
In this study, the characteristics of corrosion were described on basis previous findings rock anchors, and various factors causing explored. A investigation system anchors was established by summarizing methods for detection influencing factors. system, investigated detecting assessing environmental factors, analyzing rate morphological characteristics, testing anchoring structure, evaluating causes, development, prediction corrosion. On-site cases also examined. Results verified that is...
