以上海市苏州河河口水闸为例,根据工程所在区域的地震资料、潮汐河口水位特性、地震与高潮组合超越概率分析、相关法规要求、工程规模与重要性,并结合周边既有建筑物设防标准,确定了潮汐河口特大跨度水闸合理的抗震设防标准,并从结构方案、总体布置、基础处理、节点设计等方面提出了抗震设防措施。水闸试运行结果表明,该抗震设防标准和措施科学、可行。 Taking the sluice of Suzhou Creek in Shanghai as an example, according to the seismic data of the area where the project is located, the tidal estuary water level characteristics, the combination of the earthquake and the orgasm excess probability analysis, the relevant laws and regulations, the scale and importance of the project, , The reasonable seismic fortification standards for the large-span sluices at the tidal estuary were determined, and the seismic fortification measures were put forward from the aspects of structural scheme, overall arrangement, foundation treatment and node design. The results of sluice trial operation show that the seismic fortification standards and measures are scientific and feasible.
