【摘要】：航道测量是航道开挖阶段的一个关键环节,它对于合理组织航道开挖、质量监控、过程控制、回淤分析等方面起着十分重要的指导作用。精确航道测量为航道提供可靠的技术保证、为计算工程量提供宝贵的数据具有重要意义。同时航道测量可以有效地为建设航标、清槽捞石以及出版航道图服务提供准确的水深数据。目前全球卫星定位系统(简称GPS)已经深入到工程建设的各个领域,使得海上测量更简单、更灵活、更稳定,而且定位精度高。本文重点对天津南港航道测量方案中的深度测量进行了深入研究。主要研究了航道测量的现状,国际、国内规范要求,比较了有代表性的三种测深仪器的适用性和实用性。并通过对天津南港的地理位置、水文、气象以及通航条件分析,总结出比较适合南港航道测量的最佳时间。针对天津南港航道走向,提出了航道测量的布线方法,并提出航道测量准备工作的重要性。最后确定了航道测量的施工程序。论文的主要工作包括以下四个方面:(1)提出天津南港航道测量比较适用的高性能多波束测深仪SeaBeam1180,以及根据港口条件分析最佳测量时间,并根据回淤估算提出适宜的测量周期。(2)根据天津南港航道测量的走向线,分析港口条件确定主测深线布线方向以及根据测深仪器特点确定布线间隔、重叠宽度。(3)分析航道测量误差,为进一步提高测量精度,本文提出航道测量的前期准备工作以及要求。(4)设计航道测量的施工程序以及后期管理,包括对吃水、海况、数据采集的监测以及对数据的分析和处理。
[Abstract]:Channel surveying is a key link in channel excavation, which plays an important role in organizing channel excavation, quality monitoring, process control, siltation analysis and so on. Accurate waterway surveying provides reliable technical guarantee for waterway and provides valuable data for calculation of engineering quantity. At the same time, the waterway surveying can provide accurate depth data for the construction of navigation mark, the dredging of channel and the publication of waterway map. At present, GPS (Global Positioning system) has been in every field of engineering construction, which makes marine measurement simpler, more flexible, more stable, and has high positioning accuracy. In this paper, the depth survey in the hydrographic scheme of Tianjin Nangang is studied in detail. This paper mainly studies the present situation of waterway surveying and the requirements of international and domestic codes, and compares the applicability and practicability of three kinds of representative sounder. Through the analysis of the geographical location, hydrology, meteorology and navigation conditions of Nangang in Tianjin, the best time for channel survey in Nangang is concluded. The routing method of waterway survey and the importance of the preparation of waterway survey are put forward in view of the waterway strike of the South Port of Tianjin. Finally, the construction procedure of waterway survey is determined. The main work of this paper includes the following four aspects: (1) the high performance multi-beam sounder SeaBeam1180, which is suitable for the navigation survey of Nangang in Tianjin, is proposed, and the optimum measuring time is analyzed according to the port conditions. Based on the estimation of siltation, an appropriate survey period is put forward. (2) according to the strike line of the channel survey of the South Port of Tianjin, the direction of the main bathymetric line is determined by analyzing the port conditions, and the routing interval is determined according to the characteristics of the sounder. In order to further improve the surveying accuracy, this paper puts forward the preliminary preparation work of waterway surveying and the requirement of. 4) designing the construction procedure and later management of waterway surveying, including draught, sea condition, etc. Monitoring of data acquisition and analysis and processing of data.
