Features: This book is divided into six chapters, introducing the current research status of local scour at pier foundations both domestically and internationally, the study on local scour at pile groups of the Sutong Bridge pier foundation in the Yangtze River Estuary, the research on local scour during the sinking process of large steel caisson pier foundations, the study on scour protection for the main tower pier foundation of the Sutong Bridge in the Yangtze River Estuary, construction technology and acceptance research on scour protection for main tower piers on erodible riverbeds, and preliminary monitoring results of scour protection effectiveness. This book analyzes and demonstrates the necessity of scour protection in view of the complex construction environment, strong currents, and easily erodible riverbeds in estuary bridge areas, as well as the large planar scale and high pile density of the main pier group pile structure. It also provides a preliminary summary of key technical issues in the design and construction of scour protection engineering.
