Abstract The wide range of survey of road dangerous existing stone arch bridge in service in Three Gorges reservoir area, reveals that there has been a wide range of diseases, which seriously affected the safety of their use. A wide range of diseases, from different angles, respectively, to varying degrees, affected the performance of the stone arch bridge. In this paper, multi-level fuzzy synt...

In the present study, formal safety assessment (FSA) is introduced to investigate lockage safety of LNG-fueled ships. Risk sources during lockage of LNG-fueled ships in four typical scenarios, namely, navigation between two dams, lockage, anchorage, and fueling, are identified, and studied in combination with fundamental leakage probabilities of various components of LNG storage tanks, and simu...

The daily discharge of the Chang Jiang (the Yangtze River) at Yichang (catchment area about one million square kilometres) is derived by routing the daily discharge of the Jinsha Jiang at Pingshan (catchment area about half a million square kilometres) with modelled runoff based on daily precipitation at 14 rainfall stations in the downstream Sichuan basin. Precipitation at each station is tran...

The paper examines sediment yield and its response to catchment disturbance and environmental variables in the Upper Ž . Yangtze basin, where the attention of environmentalists has been drawn to the Three Gorges Project TGP . Information about the source and conveyance of sediment from the catchment area to the Three Gorges Reservoir has implications for management strategies. Methodologies for...

The Tibetan Plateau uplift, triggered by India–Eurasia collision, is strongly associated with the evolution of Yangtze River. river great significance for understanding geomorphology modern Asian landforms and exploring response development to tectonic uplift monsoon evolution. Although numerous methods have been employed reconstruct evolutionary history River, a century old debate still persis...

The typical diseases of stone arch bridge in the Three Gorges Reservoir area are summarized through the investigation, and four kinds of typical diseases of stone arch bridges are investigated and evaluated by spatial finite element software. Based on these investigations, the limited value index of the security and the identification technology of the four typical diseases of the bridge are ob...

The direct and secondary effects of rapidly changing climate caused large rivers draining the Atlantic passive margin to incise quickly into bedrock beginning about 35,000 years ago. Measured in samples from bedrock fluvial terraces, 10-beryllium shows that both the Susquehanna and Potomac Rivers incised 10- to 20-meter-deep gorges along steep, convex lower reaches during the last glacial cycle...
