A Seawall Constructed with GFRP Bars as Structural Reinforcing

摘要

In 2016, the seaside community of Flagler Beach, FL, was one of the many communities severely impacted and battered by Hurricane Matthew. To help mitigate the effects of future storms, a secant-pile seawall is being constructed east of State Road AlA (SR A1 A) at Flagler/Beverly Beach in the northeastern section of Flagler County, FL. When completed, the new barrier will extend 1.5 km (almost 5000 ft). To ensure that the protective system remains resilient for decades, the project is being built using concrete reinforced with glass-fiber-reinforced polymer (GFRP) bars. The secant piles have been completed, and the seawall pile cap with vegetative cover is expected to be substantially completed by October 2019.%En 2016, la comunidad costera de Flagler Beach, FL, fue severamente impactada por el huracán Matthew. Para ayudar a mitigar los efectos de futuras tormentas, se está construyendo un dique de contención de pilotes secantes de concreto al este de la carretera estatal AlA. El dique de contención se compone de barras de refuerzo de polímero reforzado con fibra de vidrio (GFRP por sus siglas en inglés) en sus 1847 pilotes secantes y cabezal continuo. Se espera que las barras GFRP no corrosivas proporcionen costos mínimos de mantenimiento y reparación a lo largo del ciclo de vida del dique de contención.
