浅析受滨海潮汐作用影响的抽水试验

Brief Analysis on Pumping Test of The Influence of Coastal Tidal

滨海地区地下水与海水有较强的水力联系。在做抽水试验的过程中,地下水位呈周期性的变化。通过工程实践,对地下水位受潮汐作用的影响进行了分析,对实测的Q(S)-t曲线进行修正,取得了较准确的水文地质参数。

Groundwater and seawater has strong hydraulic connection in the coastal area. In the process of pumping test, groundwater appear periodic fluctuation. In this paper, through the engineering practice, the analysis of the underground water level is affected by coastal tidal, and the measured curve of Q（S）-t is corrected, accurate hydrogeologieal parameter is obtained.
