汕头海域海底光缆路由条件及评价

摘要

Based on the natural environment data and the field surveying data observed by multibeam system, side scan sonar,subbottom profiler,gravity core sampling in the route surveying area, we analyzed and evaluated the natural environment and engineering geologic conditions in the route area of South-East Asia Japan Cable System (Shantou segment less than 300m water depth area) in detail, and found that the natural and engineering environment in the continental shelf of the route area is suitable for cable laying, but in the region between continental shelf and continental slope the condition is relatively worse, appropriate measures should be taken before laying.%根据在东南亚至日本海底光缆汕头段(300m水深以浅)路由勘察中所获得的多波束、侧扫声纳、浅地层剖面、柱状取样等资料,结合勘察区的自然环境特征,对路由区的自然环境条件、海底工程地质条件进行了详细的分析,并对该段路南条件进行了综合评价.研究表明,此段路由在大陆架区域路由条件较好,适合海底光缆的铺设；在大陆架与大陆坡结合带路由条件相对较差,应做好应对措施.
