东海大桥桥墩过度冲刷区域防护技术研究

摘要:

东海大桥桥墩区域发生严重冲刷现象,部分群桩桥墩冲刷深度已超过设计警戒值,为确保大桥安全,对桥墩区域实施护底防护措施。本文根据东海大桥过度冲刷区域防护试验工程实践,介绍了工程的设计方案、施工工艺和关键技术以及试验效果,为类似工程提供了参考和指导。

Abstract:

Serious scour occurred in the pier area of Donghai Bridge, and the scour depth of some pile group piers has exceeded the design warning value. In order to ensure the safety of the bridge, bottom protection measures are implemented in the pier area. Based on the practice of the protection test project in the excessive scouring area of Donghai Bridge, this paper introduces the design scheme, construction technology, key technology and test effect of the project, which provides reference and guidance for similar projects.
