针对以往河流对含水层补给方式考虑的不足,基于含水层水位与河水位及河床底板高程的关系,考虑了非饱和带的影响,借助非饱和带的相关理论获得了河流对含水层的补给量的表达式,采用数值模拟方法计算了非完整河对潜水含水层的补给量,并探讨了补给量与抽水井中水位变幅和非饱和带内最大基质吸力的关系。结果表明,非饱和带内的补给量不可忽略,且井中水位变幅越小、最大基质吸力越大,则补给量越大。
In view of the shortcomings of aquifer recharge mode in the past, based on the relationship between aquifer water level and river level and riverbed floor elevation, taking into account the influence of unsaturated zone, with the help of the theory of unsaturated zone, the recharge of aquifer The numerical simulation method was used to calculate the recharge of the sub-aquifer to the non-intact river. The relationship between the recharge and the variation of water level in the pumping well and the maximum suction of the substrate in the unsaturated zone was also discussed. The results show that the recharge in the unsaturated zone can not be ignored, and the smaller the amplitude of the water level in the well, the greater the maximum suction of the matrix, the greater the recharge.
