摘　　要：考察了海岛地区的一个横断面,在双侧海潮及弱透水层引起的越流共同作用下,含水层系统中的地下水位波动;建立了数学模型,并得到了该模型的解析解;定义了含水层长度的阈值,对含水层长度及越流等因素对地下水位波动的影响进行了讨论。This paper presented the groundwater head response to dual-tide fluctuation in the transect of an island leaky aquifer system comprising a confined aquifer and its overlying semipermeable confining layer. Both layers terminate at the coastlines on two sides of the island. The mathematical model was setup and a new analytical solution was derived. The threshold value for the aquifer＇s length was defined and the influence of the aquifer＇s length and the leakage on the groundwater head fluctuation was also discussed.

关 键 词：双侧海潮 海岛含水层系统 解析解
