对堆积海岸平衡岸线轮廓的三个表达式进行了分析和对比,其中平衡岸线轮廓表达式在一定程度上包含了潮流作用对岸线塑造的影响,适用于对凹岸和沙质海岸岸线轮廓的分析,同时也适用于对凸岸和淤泥质海岸岸线轮廓的分析,因而较基本平衡岸线形态方程和B.A.保保夫堆积岸弧方程适用范围更广。利用平衡岸线轮廓表达式,对舟山群岛金塘山和册子山附近水道的两段岸线轮廓进行了分析,结果表明:两岸段均为堆积岸弧,且理论弧长与实测弧长、理论半径与实测半径的值接近,说明理论岸线与实际岸线形态吻合得较好,同时,金塘山西部岸段较册子山西部岸段岸线形态更趋稳定,但两岸线均未达到稳定状态,目前仍处于演变过程中。
The paper analyzes and contrasts the three expressions of the coastline balance shoreline profile. The balanced shoreline outline expression contains the influence of tidal current shaping to the shoreline to a certain extent, The contour analysis is also applicable to the analysis of the coastline profile of the embankment and the muddy coast so that it has a wider scope of application than the basic balanced shoreline morphological equation and the BA-BaoFu stacked shore arc equation. The contour of two shorelines of Jintang Mountain of Zhoushan Archipelago and the waterway near the Book Hill is analyzed by using the balanced shoreline contour expression. The results show that both banks accumulate shore arc, and the theoretical arc length and the measured arc length are the theoretical The values of radius and measured radius are close, which shows that the theoretical shoreline is in good agreement with the actual shoreline shape. Meanwhile, the shoreline of the western coast of Jintangshan is more stable than that of the western shoreline of the booklet, but the stability of both coastlines is not reached State, is still in the process of evolution.
