防波堤断面结构型式及护面块体稳定性模型试验研究——2008北京奥运会青岛帆船比赛基地水工模型试验

Physical Modeling on the Structure of Breakwaters and Stability of Armor Blocks:2008 Beijing Olympic Games Qingdao Sailing Competition Base

为确保2008北京奥运会青岛帆船比赛基地内工程的水工建筑物安全可靠,对给定的2种防波堤断面结构型式及护面块体稳定性进行物理模型试验。准确掌握在极端高水位、设计高水位、设计低水位和极端低水位时,SW向、25 a和50 a一遇波浪作用下,试验断面所承受的波浪作用力,及SE向50 a一遇波浪作用下块体的稳定重量。并绘制各工况1%峰值波压力分布图,得出断面波压力的分布规律。对断面结构和护面块体稳定性进行分析。

To make the marine structures of the Qingdao Olympic Games sailing base reliable, the physical modeling of two kinds of breakwaters and the stability ofarmor blocks are perrowed Under the wave conditions of different water levels, directions and return periods, the wave pressures and stable weights of the armor blocks are investigated. The results include the optimized style of breakwater and the distribution of the wave pressures. The rationality of the section structure and stability of armor blocks are analyzed.
