一、前言石臼所位于山东省南部日照县境内,北距青岛65浬,南距连云港40浬。即将兴建的石臼深水人港初定位于日照县石臼镇东北侧石臼咀处。由于突堤的修建,破坏了原来海岸的平衡而引起岸线新的调整。本文将利用波能法公式计算石臼咀附近沿岸输沙量,并对石臼咀突堤兴建后石臼港附近海岸可能产生的海岸变形进行初步分析。 I. Introduction Shijiu is located in Rizhao County, southern Shandong Province, 65 km north of Qingdao, Nan Lianyungang 40 浬. Shijiu deep water about to be built early Hong Kong people located in Rizhao County Shijiu town northeast Shijiu Tsui. Due to the construction of the jetty, the balance of the original coast was destroyed, causing a new adjustment of the coastline. In this paper, we will calculate the sediment discharge along the Shijiuzui coast by using the formula of wave energy and conduct a preliminary analysis of the coastal deformation that may occur in the vicinity of Shijiugang after the construction of the Shijiaju Jetty.
