强浪条件下的深水防波堤施工技术
|
摘要
针对在建的以色列阿什杜德港主防波堤延伸工程在施工中存在的抛石工程量大、波浪条件差等困难,在对施工组织进行细化的基础上,通过二维和三维物理模型试验确定施工期块石稳定极限波高,合理安排施工工序,进行越冬防护结构的设计与实施。通过二维波浪模拟预报对施工进度进行动态管控,确保工程的顺利实施,为类似海况条件下的深水防波堤施工提供借鉴。
To solve the problems such as large quantity of rock dumping and bad wave condition in the main breakwater extension construction of Hadarom Port at Ashdod,Israel,we carried out the 2 D & 3 D physical model tests,based on which,we determine the wave condition limit for different layers of rocks,optimize the construction schedule, design and implement the winter protection structure. We also carried out dynamic control of the construction schedule based on the 2 D wave simulation prediction to ensure successful implementation of the project and meanwhile provide reference for the deep-water breakwater construction under similar wave condition.
