摘要
以龙泉港出海闸为例,分析感潮河口闸下冲刷破坏机理,进行除险加固方案设计,并对水闸除险加固后安全运行进行研究,主要方法是采取现场水文试验率定出过闸流量与水位及水位差的关系,结合加固护底及外侧滩地不冲流速的计算结果,进一步优化水闸运行调度方案,可供类似工程参考。
Taking Longquan port offshore sluice as an example,mechanism of erosion damage under tidal estuary sluice was analyzed,reinforcement scheme was designed,and safe operation of sluice after reinforcement was studied.The main method was to calibrate the relationship between the sluice flow rate and the water level and the water level difference using on-site hydrological test,combined with the calculation results of the reinforced bottom protection and the non-washing velocity of the outer beach,to further optimize the sluice operation scheduling scheme,which could be used as a reference for similar projects.
