Abstract
In order to solve the stability problem of breakwaters under different wave element conditions,the upgrading and renovation project of Shunxin Fishing Port in Haiyang City,Shandong Province was taken as the research object.A physical simulation test model of hydraulic cross-sections was established using indoor testing meth-ods,and the stability of three different hydraulic cross-sections and the maximum bottom flow velocity in front of the breakwater were studied.The results show that under extreme high water levels,H1% regular waves and H13% irregular waves,the breast wall of section A(top elevation 7.7 m)is unstable with a large amount of overtopping,while the breast wall,protective surface blocks,and bottom protection stones of section remain stable under other working conditions;Under the action of extreme high water level,design high water level,and design low water level,H1%,H5% and H13% regular and irregular waves,the components of section C(top elevation 8.5 m)and section B(top elevation 8.5 m)remain stable;The maximum bottom flow velocity in front of the embankment for sections A,B and C can reach 3.8 m/s,and the corresponding stable weight of bottom protection stones is 150～400 kg and is consistent with the experimental observation results.关键词
