因垦区防护标准提高及海堤存在安全隐患,外走马埭海堤需提级加固。该文通过海堤不同加高培厚方案及多种混凝土人工块体护坡的技术经济比选,确定在旧海堤迎水坡采用混凝土栅栏板护坡增加消浪效果,以尽量少加高堤顶,减小堤身提级加固增加的滑动力;在海堤内外坡脚增加压载提高抗滑力,满足海堤提级及加固双需求。
Due to the improvement of the reclamation area protection standards and the seawalls, there are potential safety problems. This article through the seawall different elevation plan and a variety of concrete artificial block slope protection of the technical and economic comparison, to determine the old seawall embankment slope fence with concrete to increase the anti-wave effect, in order to increase the dike as little as possible, less The small dike enhances and reinforces the increased sliding force; increasing the ballast to increase the anti-skidding force in the outer and inner dike foot to meet the dual requirements of seawall upgrading and reinforcement.
