台风损毁后某护岸修复方案研究

本文结合我国东南沿海某护岸受台风损毁修复工程,根据台风损毁后护岸的破坏情况,结合工程所在海域的潮流、波浪等自然条件,分析堤身损毁的原因,在现场调研基础上,经过断面物理模型试验研究、验证,提出合理可行的护岸修复方案.护面采用1:1.25的陡坡设计,既体现了集约型使用海域的要求,又增大了陆域使用面积;在大于10 s的较长周...

Research on Renovation Strategy of Typhoon-damaged Revetment

Based on a renovation project of typhoon damaged revetment in the southeast coast of China,combined with the natural conditions such as tide, waves and so on, the causes of revetment damage are analyzed.Based on the results of field investigation and cross-section model test, a reasonable and feasible revetment repair program is proposed. Steep slope design of 1:1.25 is adopted for the armor block, which not only reflects the requirements of intensive use of the sea area, but also increases the use area of the land area. Under the action of waves with a longer period of more than 10 s, it is suggested that the weight of armor blocks calculated according to the code formula should be increased appropriately. Armor blocks are placed regularly above the designed low water level and randomly below the designed low water level, with good integrity and beautiful appearance on the water and good stability and easy construction under the water.
