蜀山背斜岩溶水系统特征研究

为了岩溶水的合理利用，根据物探及水源井资料，对蜀山背斜岩溶水水文地质特征进行了研究。结果表明：蜀山背斜寒武-奥陶系碳酸盐岩岩溶发育程度主要受岩性、构造及埋藏条件等因素的控制，可溶成份含量高的地层、构造发育强烈的地段及碳酸盐岩埋藏浅的地区岩溶发育程度相对较高，相反，岩溶发育程度较低；岩溶水主要接受上覆孔隙水的垂向越流补给，其次为裸露区大气降水入渗，主要排泄途径为人工开采及侧向排泄；岩溶水水位总体上随气候与气象呈周期性变化，基本处于动态平衡状态；岩溶水水质良好，水化学类型主要为SO4·HCO3-Ca·Mg型，水质在枯水期与丰水期的变化不明显。

A Study on the Shushan Anticline Karstic Water System Characteristics

For the rational utilization of karstic water, preliminarily studied the Shushan anticline karstic hydrogeological characteristics based on geophysical prospecting and water source well data. The results showed that the Cambro-Ordovician carbonate rock karstic development extent is controlled by litbologic, structural and burying conditions. Karst is well developed in areas with high content of dissoluble component strata, tectonically active sectors, carbonate rock shallow buried areas, and vice versa. The main karst water source is from vertical leakage of overlying porous aquifers, the second is atmospheric precipitation infiltration in naked areas, while the main discharge paths are mining and lateral discharge. In the mass, karstic water level takes on periodic variation along with climate and atmospheric phenomena, basically on dynamic balancing status. Karstic water has good quality, mainly belongs to SO4· HCO3-Ca-Mg type, variation in dry season and wet season is not clear.
