Prefabricated concrete structure is an important aspect of the building development in China, while grouted sleeve connection represents a key tool for on prefabricated parts. Various grouting defects may arise during prefabrication and actual construction processes, thereby causing unsafe among components. Here, we report determination mechanical properties full-grouted with defects，using defe...

When the tunnel and underground engineering construction encounters water-rich soft broken surrounding rock, it is very easy to occur serious disasters such as mud inrush, water inrush collapse, threatening safety of construction. Taking ultracataclasite stratum exposed by 4th branch Xianglushan Tunnel in Central Yunnan Water Diversion Project an example, this has strong compactness, weak perme...

Temperature is one of the main loads super-high arch dams. (1) Background: a dam in southwest China was taken as an example this paper and temporal-spatial evolution law temperature analyzed based on monitoring data. (2) Methods: finite element simulation analysis method adopted to invert boundary conditions upstream surface thermal parameters concrete, process long-term operation simulated ana...
