摘　　要：杏林湾泄洪排涝隧洞上游连接水库,下游连接外海。试验以特征频率(P=0.02%)时的库水位为依据,研究不同潮水位与泄流量的关系、进出口流态、下游流速分布及消能防冲措施。根据试验成果,推荐用"混凝土+防淘墙+堆石"为消能防冲设施。The tunnel is laid across the sea embankment to release floodwater and drain waterlog from Xinglinwan reservoir to outside sea. Taking the reservoir level with characteristic frequency（p = 0.02% ）as test basis to study the relationship between tunnel discharge and tidal stage, the flow condition and velocity distribution at tunnel entrance and exit, the downstream energy dissipation and scour condition. According to the test result, the energy dissipation and anti-scour scheme consisted of ＂concrete block pitching ＋ anti-scour wall ＋ riprapping＂ is recommended.
