【摘要】 广东省韶关市是一个以石灰岩地层为主的山区重工业发展城市,城镇居民饮用水源主要是抽取武江河水,部分厂矿及居民生产、生活用水主要靠开采地下水解决,而所开采的地下水,以覆盖型岩溶水为主。由于可溶岩的岩溶发育程度具有明显的不均匀性,因而富水性也有较大的差异。基于合理有效地开发利用岩溶地下水资源,解决岩溶石山地区厂矿、居民的生产、生活用水,作者通过对韶关市水文工程环境地质综合调查及韶关市供水水文地质勘探的大量资料分析总结,并参考相关文献,认为韶关市岩溶发育仍有规律可循,其岩溶发育及富水性有如下特点:(1)质纯厚层结构单一的碳酸盐岩岩溶最发育,富水性强;(2)地下水径流强烈及排泄地带岩溶发育,富水性强;(3)沿断裂交汇部位及褶曲轴部岩溶发育,富水性强。更多还原

【Abstract】 The Shaoguan city is a heavy industrial city located in a mountainous area dominated with limestone strata in Guangdong province. The source of drinking water for urban dwellers is mainly from Wujiang River,but partial water used for mining production,industrial use and drinking for local residents is from underground water,which is mainly the covered karst water. Due to the apparent unevenness of the karst development in soluble rocks,therefore,it results in a great difference of water yield. To exploit underground karst water reasonably and effectively so as to solve water-lacking problems of supplying production for factories and mines and drinking water supplies for local residents,it is necessary to study the karst development mechanism and its relationship with water yield property in this area. Based on a comprehensive analysis on the hydrogeological,engineering geological and environmental geological survey as well as a great deal of hydrogeological prospecting data in Shaoguan city and relevant references,the karst development mechanism is discussed in this paper. The authors think there are still certain development regularities of karst development in Shaoguan area. The karst and water yield developed mostly in the following areas: ( 1) simple structure of thick-layered pure carbonate; ( 2) underground water runoff and drainage areas; ( 3) fault intersection and fold shaft areas.更多还原
