以长兴潜堤后方滩涂圈围工程为例,分别运用超短基线技术与旁侧声呐技术检测软体排铺设成型质量,研究表明:超短基线技术能够测得实时、精度较高的典型段排体铺设成型信息,但操作复杂;旁侧声呐技术可检测软体铺排整体搭接情况,但其精度和时效性较低。采用超短基线技术与旁侧声呐技术相结合的方法,可同时获取实时、高精度、全面的软体排铺设成型数据,能够有效控制深水筑堤水下软体排铺设质量。
Taking Changxing submerged embankment behind the mudflat encirclement project as an example, we use the short-baseline technology and the lateral sonar technology respectively to detect the forming quality of the software stack. The results show that the ultra-short baseline technology can measure the real- Pavement information, but the operation is complex; side sonar technology can detect the overall software lap row overlap, but its accuracy and timeliness is low. Using the combination of ultra-short baseline technology and lateral sonar technology, real-time, high-precision and comprehensive software layout data can be obtained at the same time, which can effectively control the quality of underwater soft-ware row laying in deep-water embankment.
