摘要:
以三门核电一期取水口为例,其周边的宁海县双盘涂、三山涂2处围涂,一旦实施后会引起该取水口附近海床面的淤高,取水口高程能否能满足正常取水的需求,对三门核电厂今后安全运营至关重要.水槽试验结果表明,各组次下取水口的高程富余量在1.20~2.80 m.当取水口处于取水状态时,其高程富余量可较不取水状态下增大约1/6~1/4.无论取水与否,随着床面的淤高,取水立管的桩柱绕流效应大幅减弱,各取水窗四周的局部冲刷深度均随之减小,从而导致取水口高程富余量的迅速减小,但高程富余量仍在1.00 m以上,不会对今后取水口的正常取水造成威胁.通过试验研究,对周边围涂实施后取水口的局部冲刷形态有了新的认识,对取水口设计高程的富余程度有了科学的评估和论证.
Abstract:
Taking the water intakes of first-stage project of Sanmen Nuclear power plant as an example,it is very important for the effective operation of the plant whether the elevation of the water intakes can meet the requirements for normal water intaking due to the deposition of seabed around the water intakes after the implementation of the Shuangpan reclamation and the Sanshan reclamation in Ninghai County.The flume model tests show that,the elevation margins of the water intakes of each group are between 1.2 meters to 2.8 meters.When the water intakes are in the water state,the elevation margins can be increased about 1/6 to 1/4 than the ones without the water state.Whether the water intakes are in the water state,with the gradual deposition of seabed,the depth of the erosion around the top of the water intakes decrease because of the significantly decrease of the effects of the flow around the pile column,then the elevation margins of the water intakes decrease quickly,but still in 1m above,which has no threat to the future of normal water intaking of the water intakes.Through the tests research,we have a new understanding on the morphology of the local erosion of the water intakes after the implementation of the surrounding reclamations,and we also have a scientific evaluation and demonstration of the margin degree of the design elevation of the water intakes,which is of great scientific and engineering significance.
