In recent years, high-speed railways in China have developed very rapidly, and the number
and span of the railway bridges are keeping increasing. Meanwhile, frequent extreme …

The damage and collapse of the reinforced concrete (RC) piers subjected to rockfall impact
occur frequently in mountainous areas. In the present scrutiny, a full-scale numerical model …

Given the limited dissipating effect and high construction costs of traditional sand cushion in
shed, this paper proposes to partially replace the sand with waste tennis balls to solve the …

Continuous rigid-frame bridges across valleys are often at risk of rockfalls caused by heavy
rainfalls, earthquakes, and debris flow in a mountainous environment. Hollow thin-walled …

Rockfall disasters pose a significant threat in mountainous areas, leading to severe damage
and potential collapse of transportation infrastructure. On the other hand, the concrete and …

Disadvantages of semi-rigid materials bring a significant challenge to the maintenance of
the semi-rigid base pavement. The micro-cracking treatment employs the falling weight to …

Concrete dams are reliable when subjected to static loads such as earth pressure and water
pressure. However, the dam failure would be abrupt and catastrophic if it is impacted by …

Railway bridges in mountainous regions are susceptible to damage and collapse due to
rockfall impacts, posing a risk to train operations. This research specifically focuses on risk …

Recently, hollow reinforced concrete (RC) piers have been increasingly utilized in bridge
structures located in mountainous regions, owing to their high strength-to-mass ratio and …
