碳酸盐岩中喀斯特水的“多元”空隙研究

Study on multivairate porous medium of Carbonate rocks

喀斯特水的特征与其他岩石中的裂隙水、孔隙水具实质性区别,主要原因是碳酸盐岩发育有多元空隙,导致喀斯特化岩体中的水介质复杂多样性。为便於深入研究,本文把喀斯特水运动归纳为两个类型:(1)不纯碳酸盐岩、结晶白云岩、中国北方的灰岩中的溶隙水,流态为层流运动;(2)中国南方的灰岩中的溶洞水(指Ⅲ水动力带),流态为紊流运动。

A series of characteritics of karst water have basic differences from that of fissure water and porous water, the main cause is that a multivariate porous medium has developed in the carbonate rocks,which also causes the water-bearing medium of karst rocks move compli-cated.For the sake of further studying the movement of karst water,the author suggests that all of the karst water should be divided into two categogies:I)The karst water in the impure carbonate rocks,dolonite with crystalline texture and limestone in northe China can be in-cluded in corrosional fissure water,its flow basically belongs to laminal flow.II).THe karst water in limestone in southern China is classified corrosive cave water (refering to the third hydrodynamic zone)its flow belongs to turblent flow.the later is the principal direction of study in current academic circles.
