高精度准实时监测防波堤抛石的软件开发

在长周期波浪、作业窗口少等不利海况条件下,传统的多波束监测技术精度仅为±10 cm、效率也较低。依托以色列阿什杜德港工程,基于多波束通用格式数据,采用有验潮和无验潮两种测量模式,分析各种误差来源,并对多种滤波算法进行对比,开发出多波束高精度自动化后处理软件。结果表明,该软件可实现不利海况条件下的防波堤边坡抛石状态准实时监测,精度可达±5 cm。

Software development of high precision and quasi real-time monitoring of breakwater riprap

Under adverse sea conditions such as long period waves and few construction period,the traditional multi-beam monitoring technology has low precision,only ±10cm.Relying on the Ashdod port project in Israel,we analyze the various error sources with and without tide testing based on the common format data of multi-beam,compare a variety of filtering algorithms,and develop the multi-beam high-precision automatic post-processing software.The results show that the software can achieve quasi real-time monitoring of the riprap state of the slope under adverse sea conditions with an precision of ±5 cm.
