摘要
本文通过对广花盆地主要含水碳酸盐岩层区248个钻孔资料的分析,认为广花盆地内岩溶的发育主要分布在质纯的石灰岩地段,且严格受到地质构造的控制;古河道附近地区的岩溶也比较发育:广花平原地下溶洞大致可分为3层:溶洞的垂直分布随埋藏深度的增加而减弱;溶洞的充填率随埋藏深度的增加而减少,发育规模较大的溶洞充填率高;溶洞的富水性随充填物的增多而降低。
According to the analyses of 248 drill holes in water bearing carbonate rock areas of Guangzhou-Huaxian basin, the authors consider that the karst in Guangzhou-Huaxian basin is mainly distributed in pure carbonate rock areas, strictly controlled by tectonism, and is also developed near the paleochannels. The karst cave can be divided into three layers. The number of cave decreases with the increase of depth. The filling rate of cave also reduces with the increase of depth and it is higher in bigger caves. Water content in cave decreases with the increase of the filling .
