侧扫声呐在海底管线路由规划中的应用

Application of side sonic sonar in route planning of submarine pipeline

海底管线路由规划的前期调查手段主要可以通过侧扫声呐、浅地层剖面仪进行海底地貌及浅地层普查.本文通过Klein4900侧扫声呐对福清核电厂海底管线路由规划调查区域进行了海底地貌普查.根据调查结果,调查区域内主要包含礁石、沙波、冲刷沟槽、浅滩自然地貌要素,人工障碍物有养殖区、渔栅及水下残留绳索.依据调查结果绘制障碍区分布图,可以对路由规划进行调整,减少或避免与障碍区重合.

The preliminary investigation means of submarine pipeline routing planning can be mainly carried out by side scan sonar and shallow stratigraphic profiler to survey the seabed geomorphology and shallow strata. In this paper,Klein4900 side scan sonar is used to survey the submarine geomorphology in the survey area of the submarine pipeline routing planning of Fuqing nuclear power plant. According to the survey results,the survey area mainly includes natural elements such as reef,sand waves,scour grooves and shoals. Artificial barriers include aquaculture area,fishing fence and underwater residual rope. According to the results of the survey,draw the map of the obstacle area,and can adjust the route planning to reduce or avoid the overlap with the obstacle area. The application of side scan sonar in submarine pipeline routing planning has a very wide space.
