摘　　要：钱塘江河口潮强流急,属典型的强潮河口。在治江围涂工程实施过程中,抛坝促淤的堤头冲深问题引起设计和施工人员的广泛关注,砂肋软体排护底技术应用在钱塘江河口的适用性及经济性,一直没有明确结论。在余姚治江围涂工程实施过程中,通过实验室水槽铺排模拟试验和砂肋软体排护底技术的实际应用,验证砂肋软体排护底技术的设计与施工方法,取得良好的经济效益。The Qiantang Estuary is a typical macro-tide estuary with strong tide and rapid flow. During the implementation of the river regulation and reclamation project,the scour depth problem of levee head has aroused the widespread concern of designers and constructors. No clear conclusion reached on the adaptability and economical of sand-rib soft mattress applied in Qiantang Estuary. This paper presents the design and operation of sand-rib soft mattress technology during the regulation and reclamation in Yuyao,the technology has been verified by laboratory and field tests,resulting in satisfactory economic benefit,it has a certain inspiration and reference for the construction of similar projects in the future.
