岩溶含水层的边界,历来习惯于以非可溶岩层为其边界.实践证明,岩溶发育有明显的非均匀性,发育带含水,不发育带不含水的事实也是公认不讳的。 本文依非稳定流理论,根据非稳定流抽水试验资料绘制的曲线具有两个不同斜率的两直线段的特点,结合海泉水源地具体的水文地质条件,在岩溶含水层中确立了一直角隔水边界,并用水位回报的方法进行了验证。 此探讨,意在视具体条件跳出历来以非可溶岩层来定岩溶水隔水边界的习俗观念。
The boundary of karst aquifer has always been accustomed to using non-soluble rock as its boundary. Practice has proved that karst development has obvious heterogeneity, development zone with water, without development zone without water is also accepted. According to the unsteady flow theory, the curve drawn from the unsteady flow pumping test data has the characteristics of two straight line segments with different slopes. Based on the specific hydrogeological conditions of the Haiquan water source, a constant angular interval is established in the karst aquifer Water boundary, and verified by the method of water level return. This discussion is intended to jump out of the customary notion of determining the boundaries of karst water barrier with non-soluble rock layers, depending on specific conditions.
