摘　　要：根据国家海洋局印发的《海籍调查规范》,填海工程用海范围算至填海边坡水下坡脚线。在填海工程竣工验收中,水下坡脚线主要使用侧扫声纳获取。通过对侧扫声纳探测水下坡脚线位置的误差来源进行分析,提出了一系列提高侧扫声纳水下坡脚线位置探测精度的措施,并将其应用到实际工作中,对侧扫声纳水下坡脚线位置探测精度进行了验证。结果表明,侧扫声纳在填海工程水下坡脚线探测中的位置精度满足《海籍调查规范》中水下坡脚线平面位置精度要求。According to the《Specification for sea area use register investigation》issued by the state oceanic administration,the use range of sea reclamation calculates to the underwater slope foot line.In the completion and acceptance work of sea reclamation,the underwater slope foot line is maMy surveyed by sidescan sonar.This paper analyzes the source of position error of underwater slope line surveyed by sidescan sonar and proposes a series of measures to improve the position accuracy.These measures are applied to practical work to verify the accuracy of the position.The results show that the position accuracy of underwater foot line in sea reclamation surveyed by sidescan sonar can meet the requirements in《Specifications for sea area use register investigation》.
