摘要
为了对琼州海峡跨海通道中线桥梁与隧道、西线桥梁主体工程方案进行深入的研究、比选和论证,提出推荐意见,需要进行琼州海峡(西线)水下地形测量。由于海峡中间不可能设潮位站和当前测量技术较难达到1∶1 000的精度要求,为此采用无验潮技术和多波束测深技术相结合的方法,较好地完成了420 km2的水下地形测量,为琼州海峡跨海通道工程可行性研究提供了水深地形基础资料。
It is necessary to conduct an underwater topographic survey for west-line crossing project in Qiongzhou Strait, so as to put forward the recommendations for the in-depth research of sea-crossing channel. Due to unfeasibility to setting a tide gauge station in the strait and inaccessibility to the precision of 1：1000 by the current measurement technology, the underwater topographic survey covering 420 km2 area has been preferably completed by integrating the non-tidal observation technology with multi-beam sounding technology.
