摘要:
从3个方面分析了港珠澳大桥桥位附近航道演变情况,首先针对伶仃洋河口湾径流的水沙条件、桥位附近的潮流、潮位等基本特征进行分析,以确定桥位附近滩槽演变的特点和趋势;其次对桥位附近试挖槽的实测资料进行了分析,确定试挖槽在不同季节的回淤强度及挖槽边坡随时间的变化情况;最后比较了桥位附近航道不同时期测图的断面和容积的变化,分析了桥区附近的航道演变情况及演变趋势,分析结果表明各航道均处于相对稳定状态.

Abstract:
An analysis of the three aspects of waterway processes near the Hong Kong-Zhuhai-Macao Bridge is given in this paper.Firstly,in order to confirm the shoal and trough evolution characteristics and trends near the bridge,the paper focuses on basic features such as the runoff,sediment,tide level and tidal current.Secondly,based on the measured data of the test trench near the bridge,the silting intensity and slope change in different seasons are found.Finally,based on the comparison of the cross-section and volume changes of different periods of the channels near the bridge as well as the analysis of the channel evolution characteristics and development trend,an conclusion is made that each channel is in a relatively stable state.
