The damage results show that it is worse when explosive is in the water compared to when it is on the surface or at the bottom of the water. With emphasis on the case that the explosive is in the water, the dynamic response of concrete dam was simulated. The energies absorbed by dam,...
The crack and wreck of watet concrete structures is the result of inside damage and its accumulation.Because of the randomicity of materials and loads,the expanding process of cracks in the concrete structures is also stochastic.The Markov model is applied to analyze the probability of the changi...
Before pouring underwater concrete, again testing the thickness of the hole at the end of the mud settling, such as sediment thickness is greater than 5cm (piles), friction piles greater than 15cm, you must clear a second hole on the hole, make sure the hole at the end of sediment thic...
The damage prediction of concrete gravity dams under blast loads has gained importance in recent years due to the great number of accidental events and terrorist bombing attacks that affected engineering safety. It has long been known that an underwater explosion can cause significantly more damage ...
PURPOSE:To improve water permeability and obtain a water permeable concrete product with high strength, by mixing spherical particles of the by-product slag while producing ferroalloy as a concrete product used for a road. CONSTITUTION:Such slags as ferrochrome slag, ferronickel slag, ferrovanadium ...
In order to study the influence of water-cement ratio on reinforced concrete beam, the cracking load and cracking time, the position of cracks, distribution and development condition, ultimate load and time of failure of the beam were defined as main observation indexes. Nine RC beams of differe...
Excavation damage zones that occur around tunnels usually lead to a change in rock permeability, which has an impact on the water inflow into tunnels and even induces water inrush disasters. For a better understanding of the effect of the excavation dama
