本文采用数值模拟方法研究了笔架岭油田滩海公路与潮流的相互作用.根据对模拟结果的分析,认为工程方案Ⅰ和方案Ⅱ的条件下,潮流均不至于对新修路段产生严重损坏.但就潮流的冲淤效果上看,方案Ⅱ比方案Ⅰ更有利于路基的维护.风险探井路(方案Ⅲ)的走向合理,但必须在跨越大凌河东水道的路段上修筑桥涵. In this paper, the numerical simulation method is used to study the interaction between the beach and the tidal current in the Bijia Ling oil field.Based on the analysis of the simulation results, it is considered that the tidal current will not cause any serious damage to the newly constructed road section under the conditions of Project Ⅰ and Ⅱ. As far as the trend of erosion and sedimentation is concerned, the scheme II is more conducive to the maintenance of roadbed than scheme I. The exploration of the risk exploration well (scheme Ⅲ) is reasonable, but the bridges and culverts must be constructed on the sections across the Daling River.
